Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507274, here are decompositions:

3 + 31507271 = 31507274
31 + 31507243 = 31507274
157 + 31507117 = 31507274
193 + 31507081 = 31507274
367 + 31506907 = 31507274
433 + 31506841 = 31507274
577 + 31506697 = 31507274
751 + 31506523 = 31507274

Showing the first eight; more decompositions exist.
