Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32540, here are decompositions:

3 + 32537 = 32540
7 + 32533 = 32540
37 + 32503 = 32540
43 + 32497 = 32540
61 + 32479 = 32540
73 + 32467 = 32540
97 + 32443 = 32540
127 + 32413 = 32540

Showing the first eight; more decompositions exist.
