Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507150, here are decompositions:

11 + 31507139 = 31507150
41 + 31507109 = 31507150
113 + 31507037 = 31507150
173 + 31506977 = 31507150
239 + 31506911 = 31507150
263 + 31506887 = 31507150
359 + 31506791 = 31507150
401 + 31506749 = 31507150

Showing the first eight; more decompositions exist.
