Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586076, here are decompositions:

17 + 31586059 = 31586076
19 + 31586057 = 31586076
23 + 31586053 = 31586076
73 + 31586003 = 31586076
79 + 31585997 = 31586076
97 + 31585979 = 31586076
103 + 31585973 = 31586076
113 + 31585963 = 31586076

Showing the first eight; more decompositions exist.
