Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507114, here are decompositions:

5 + 31507109 = 31507114
137 + 31506977 = 31507114
227 + 31506887 = 31507114
293 + 31506821 = 31507114
593 + 31506521 = 31507114
677 + 31506437 = 31507114
761 + 31506353 = 31507114
941 + 31506173 = 31507114

Showing the first eight; more decompositions exist.
