Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551064, here are decompositions:

53 + 31551011 = 31551064
71 + 31550993 = 31551064
197 + 31550867 = 31551064
227 + 31550837 = 31551064
257 + 31550807 = 31551064
263 + 31550801 = 31551064
317 + 31550747 = 31551064
353 + 31550711 = 31551064

Showing the first eight; more decompositions exist.
