Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544284, here are decompositions:

3 + 31544281 = 31544284
71 + 31544213 = 31544284
113 + 31544171 = 31544284
131 + 31544153 = 31544284
227 + 31544057 = 31544284
251 + 31544033 = 31544284
263 + 31544021 = 31544284
293 + 31543991 = 31544284

Showing the first eight; more decompositions exist.
