Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589254, here are decompositions:

3 + 31589251 = 31589254
71 + 31589183 = 31589254
167 + 31589087 = 31589254
197 + 31589057 = 31589254
227 + 31589027 = 31589254
311 + 31588943 = 31589254
647 + 31588607 = 31589254
761 + 31588493 = 31589254

Showing the first eight; more decompositions exist.
