Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507036, here are decompositions:

59 + 31506977 = 31507036
107 + 31506929 = 31507036
149 + 31506887 = 31507036
227 + 31506809 = 31507036
293 + 31506743 = 31507036
317 + 31506719 = 31507036
347 + 31506689 = 31507036
359 + 31506677 = 31507036

Showing the first eight; more decompositions exist.
