Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507362, here are decompositions:

11 + 31507351 = 31507362
41 + 31507321 = 31507362
43 + 31507319 = 31507362
79 + 31507283 = 31507362
151 + 31507211 = 31507362
163 + 31507199 = 31507362
181 + 31507181 = 31507362
223 + 31507139 = 31507362

Showing the first eight; more decompositions exist.
