Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595384, here are decompositions:

13 + 31595371 = 31595384
211 + 31595173 = 31595384
283 + 31595101 = 31595384
397 + 31594987 = 31595384
421 + 31594963 = 31595384
523 + 31594861 = 31595384
571 + 31594813 = 31595384
577 + 31594807 = 31595384

Showing the first eight; more decompositions exist.
