Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514482, here are decompositions:

3 + 31514479 = 31514482
5 + 31514477 = 31514482
53 + 31514429 = 31514482
59 + 31514423 = 31514482
173 + 31514309 = 31514482
191 + 31514291 = 31514482
401 + 31514081 = 31514482
743 + 31513739 = 31514482

Showing the first eight; more decompositions exist.
