Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596876, here are decompositions:

19 + 31596857 = 31596876
29 + 31596847 = 31596876
37 + 31596839 = 31596876
79 + 31596797 = 31596876
83 + 31596793 = 31596876
107 + 31596769 = 31596876
127 + 31596749 = 31596876
163 + 31596713 = 31596876

Showing the first eight; more decompositions exist.
