In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: 2 primes that equal
Hi;
Too bad you only want two primes
1000 = 29 x 31 + 11 - 37 - 7 x 17+41 x 2 x 3

Re: 2 primes that equal
cube(2) × cube(5) = 1000
(NB: I write cube(n) instead of n3 in case the exponent is mistaken for an extra number.)

Oops! Off to a great start for the new year I am!
Should have been 1997-997.

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Prime numbers have got to be the neatest things; they are like atoms. Composites are two or more primes held together by multiplication.
In biology, we use math like we know what we are talking about. Sad isn't it.
