Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596578, here are decompositions:

7 + 31596571 = 31596578
37 + 31596541 = 31596578
67 + 31596511 = 31596578
199 + 31596379 = 31596578
271 + 31596307 = 31596578
457 + 31596121 = 31596578
571 + 31596007 = 31596578
709 + 31595869 = 31596578

Showing the first eight; more decompositions exist.
