Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507364, here are decompositions:

3 + 31507361 = 31507364
13 + 31507351 = 31507364
43 + 31507321 = 31507364
67 + 31507297 = 31507364
277 + 31507087 = 31507364
283 + 31507081 = 31507364
433 + 31506931 = 31507364
457 + 31506907 = 31507364

Showing the first eight; more decompositions exist.
