Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595088, here are decompositions:

29 + 31595059 = 31595088
67 + 31595021 = 31595088
79 + 31595009 = 31595088
89 + 31594999 = 31595088
97 + 31594991 = 31595088
101 + 31594987 = 31595088
127 + 31594961 = 31595088
157 + 31594931 = 31595088

Showing the first eight; more decompositions exist.
