Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514960, here are decompositions:

13 + 31514947 = 31514960
67 + 31514893 = 31514960
229 + 31514731 = 31514960
271 + 31514689 = 31514960
307 + 31514653 = 31514960
331 + 31514629 = 31514960
409 + 31514551 = 31514960
487 + 31514473 = 31514960

Showing the first eight; more decompositions exist.
