Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595116, here are decompositions:

53 + 31595063 = 31595116
107 + 31595009 = 31595116
197 + 31594919 = 31595116
233 + 31594883 = 31595116
239 + 31594877 = 31595116
317 + 31594799 = 31595116
347 + 31594769 = 31595116
359 + 31594757 = 31595116

Showing the first eight; more decompositions exist.
