Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507332, here are decompositions:

11 + 31507321 = 31507332
13 + 31507319 = 31507332
61 + 31507271 = 31507332
89 + 31507243 = 31507332
151 + 31507181 = 31507332
173 + 31507159 = 31507332
193 + 31507139 = 31507332
223 + 31507109 = 31507332

Showing the first eight; more decompositions exist.
