Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595118, here are decompositions:

17 + 31595101 = 31595118
59 + 31595059 = 31595118
97 + 31595021 = 31595118
109 + 31595009 = 31595118
127 + 31594991 = 31595118
131 + 31594987 = 31595118
157 + 31594961 = 31595118
199 + 31594919 = 31595118

Showing the first eight; more decompositions exist.
