Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595150, here are decompositions:

151 + 31594999 = 31595150
163 + 31594987 = 31595150
277 + 31594873 = 31595150
283 + 31594867 = 31595150
337 + 31594813 = 31595150
421 + 31594729 = 31595150
523 + 31594627 = 31595150
541 + 31594609 = 31595150

Showing the first eight; more decompositions exist.
