Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586064, here are decompositions:

5 + 31586059 = 31586064
7 + 31586057 = 31586064
11 + 31586053 = 31586064
61 + 31586003 = 31586064
67 + 31585997 = 31586064
101 + 31585963 = 31586064
127 + 31585937 = 31586064
227 + 31585837 = 31586064

Showing the first eight; more decompositions exist.
