Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456110, here are decompositions:

11 + 31456099 = 31456110
17 + 31456093 = 31456110
31 + 31456079 = 31456110
43 + 31456067 = 31456110
89 + 31456021 = 31456110
97 + 31456013 = 31456110
107 + 31456003 = 31456110
149 + 31455961 = 31456110

Showing the first eight; more decompositions exist.
