Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507326, here are decompositions:

5 + 31507321 = 31507326
7 + 31507319 = 31507326
29 + 31507297 = 31507326
43 + 31507283 = 31507326
83 + 31507243 = 31507326
127 + 31507199 = 31507326
167 + 31507159 = 31507326
239 + 31507087 = 31507326

Showing the first eight; more decompositions exist.
