Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595492, here are decompositions:

109 + 31595383 = 31595492
241 + 31595251 = 31595492
283 + 31595209 = 31595492
433 + 31595059 = 31595492
619 + 31594873 = 31595492
631 + 31594861 = 31595492
811 + 31594681 = 31595492
883 + 31594609 = 31595492

Showing the first eight; more decompositions exist.
