Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620796, here are decompositions:

3 + 31620793 = 31620796
17 + 31620779 = 31620796
47 + 31620749 = 31620796
59 + 31620737 = 31620796
113 + 31620683 = 31620796
197 + 31620599 = 31620796
227 + 31620569 = 31620796
353 + 31620443 = 31620796

Showing the first eight; more decompositions exist.
