Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465956, here are decompositions:

107 + 31465849 = 31465956
127 + 31465829 = 31465956
167 + 31465789 = 31465956
199 + 31465757 = 31465956
229 + 31465727 = 31465956
283 + 31465673 = 31465956
293 + 31465663 = 31465956
307 + 31465649 = 31465956

Showing the first eight; more decompositions exist.
