Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595062, here are decompositions:

3 + 31595059 = 31595062
41 + 31595021 = 31595062
53 + 31595009 = 31595062
71 + 31594991 = 31595062
101 + 31594961 = 31595062
131 + 31594931 = 31595062
179 + 31594883 = 31595062
251 + 31594811 = 31595062

Showing the first eight; more decompositions exist.
