Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545016, here are decompositions:

47 + 31544969 = 31545016
53 + 31544963 = 31545016
137 + 31544879 = 31545016
197 + 31544819 = 31545016
233 + 31544783 = 31545016
257 + 31544759 = 31545016
359 + 31544657 = 31545016
443 + 31544573 = 31545016

Showing the first eight; more decompositions exist.
