Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544260, here are decompositions:

47 + 31544213 = 31544260
53 + 31544207 = 31544260
71 + 31544189 = 31544260
89 + 31544171 = 31544260
107 + 31544153 = 31544260
227 + 31544033 = 31544260
239 + 31544021 = 31544260
263 + 31543997 = 31544260

Showing the first eight; more decompositions exist.
