Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605796, here are decompositions:

17 + 31605779 = 31605796
23 + 31605773 = 31605796
83 + 31605713 = 31605796
107 + 31605689 = 31605796
239 + 31605557 = 31605796
353 + 31605443 = 31605796
389 + 31605407 = 31605796
419 + 31605377 = 31605796

Showing the first eight; more decompositions exist.
