Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514908, here are decompositions:

59 + 31514849 = 31514908
71 + 31514837 = 31514908
137 + 31514771 = 31514908
167 + 31514741 = 31514908
281 + 31514627 = 31514908
431 + 31514477 = 31514908
479 + 31514429 = 31514908
599 + 31514309 = 31514908

Showing the first eight; more decompositions exist.
