Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456104, here are decompositions:

5 + 31456099 = 31456104
11 + 31456093 = 31456104
37 + 31456067 = 31456104
83 + 31456021 = 31456104
101 + 31456003 = 31456104
157 + 31455947 = 31456104
227 + 31455877 = 31456104
263 + 31455841 = 31456104

Showing the first eight; more decompositions exist.
