Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586950, here are decompositions:

11 + 31586939 = 31586950
23 + 31586927 = 31586950
29 + 31586921 = 31586950
47 + 31586903 = 31586950
71 + 31586879 = 31586950
137 + 31586813 = 31586950
233 + 31586717 = 31586950
251 + 31586699 = 31586950

Showing the first eight; more decompositions exist.
