Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595372, here are decompositions:

163 + 31595209 = 31595372
199 + 31595173 = 31595372
271 + 31595101 = 31595372
313 + 31595059 = 31595372
373 + 31594999 = 31595372
409 + 31594963 = 31595372
499 + 31594873 = 31595372
643 + 31594729 = 31595372

Showing the first eight; more decompositions exist.
