Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596838, here are decompositions:

17 + 31596821 = 31596838
41 + 31596797 = 31596838
89 + 31596749 = 31596838
131 + 31596707 = 31596838
167 + 31596671 = 31596838
227 + 31596611 = 31596838
401 + 31596437 = 31596838
419 + 31596419 = 31596838

Showing the first eight; more decompositions exist.
