Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586050, here are decompositions:

47 + 31586003 = 31586050
53 + 31585997 = 31586050
71 + 31585979 = 31586050
113 + 31585937 = 31586050
227 + 31585823 = 31586050
233 + 31585817 = 31586050
239 + 31585811 = 31586050
269 + 31585781 = 31586050

Showing the first eight; more decompositions exist.
