Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595162, here are decompositions:

61 + 31595101 = 31595162
103 + 31595059 = 31595162
163 + 31594999 = 31595162
199 + 31594963 = 31595162
349 + 31594813 = 31595162
433 + 31594729 = 31595162
463 + 31594699 = 31595162
661 + 31594501 = 31595162

Showing the first eight; more decompositions exist.
