Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596090, here are decompositions:

23 + 31596067 = 31596090
41 + 31596049 = 31596090
61 + 31596029 = 31596090
83 + 31596007 = 31596090
101 + 31595989 = 31596090
107 + 31595983 = 31596090
223 + 31595867 = 31596090
257 + 31595833 = 31596090

Showing the first eight; more decompositions exist.
