Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589650, here are decompositions:

17 + 31589633 = 31589650
83 + 31589567 = 31589650
89 + 31589561 = 31589650
137 + 31589513 = 31589650
167 + 31589483 = 31589650
227 + 31589423 = 31589650
311 + 31589339 = 31589650
317 + 31589333 = 31589650

Showing the first eight; more decompositions exist.
