Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595058, here are decompositions:

37 + 31595021 = 31595058
59 + 31594999 = 31595058
67 + 31594991 = 31595058
71 + 31594987 = 31595058
97 + 31594961 = 31595058
127 + 31594931 = 31595058
139 + 31594919 = 31595058
151 + 31594907 = 31595058

Showing the first eight; more decompositions exist.
