Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507134, here are decompositions:

17 + 31507117 = 31507134
47 + 31507087 = 31507134
53 + 31507081 = 31507134
97 + 31507037 = 31507134
157 + 31506977 = 31507134
223 + 31506911 = 31507134
227 + 31506907 = 31507134
293 + 31506841 = 31507134

Showing the first eight; more decompositions exist.
