Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595360, here are decompositions:

109 + 31595251 = 31595360
151 + 31595209 = 31595360
373 + 31594987 = 31595360
397 + 31594963 = 31595360
457 + 31594903 = 31595360
487 + 31594873 = 31595360
499 + 31594861 = 31595360
547 + 31594813 = 31595360

Showing the first eight; more decompositions exist.
