Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507576, here are decompositions:

3 + 31507573 = 31507576
5 + 31507571 = 31507576
53 + 31507523 = 31507576
173 + 31507403 = 31507576
257 + 31507319 = 31507576
293 + 31507283 = 31507576
467 + 31507109 = 31507576
599 + 31506977 = 31507576

Showing the first eight; more decompositions exist.
