Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582086, here are decompositions:

37 + 31582049 = 31582086
43 + 31582043 = 31582086
59 + 31582027 = 31582086
83 + 31582003 = 31582086
89 + 31581997 = 31582086
103 + 31581983 = 31582086
113 + 31581973 = 31582086
139 + 31581947 = 31582086

Showing the first eight; more decompositions exist.
