Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595156, here are decompositions:

97 + 31595059 = 31595156
157 + 31594999 = 31595156
193 + 31594963 = 31595156
283 + 31594873 = 31595156
349 + 31594807 = 31595156
409 + 31594747 = 31595156
457 + 31594699 = 31595156
547 + 31594609 = 31595156

Showing the first eight; more decompositions exist.
