Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507224, here are decompositions:

13 + 31507211 = 31507224
43 + 31507181 = 31507224
107 + 31507117 = 31507224
137 + 31507087 = 31507224
251 + 31506973 = 31507224
293 + 31506931 = 31507224
313 + 31506911 = 31507224
317 + 31506907 = 31507224

Showing the first eight; more decompositions exist.
