Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507416, here are decompositions:

13 + 31507403 = 31507416
53 + 31507363 = 31507416
97 + 31507319 = 31507416
173 + 31507243 = 31507416
257 + 31507159 = 31507416
277 + 31507139 = 31507416
307 + 31507109 = 31507416
379 + 31507037 = 31507416

Showing the first eight; more decompositions exist.
