Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595984, here are decompositions:

103 + 31595881 = 31595984
151 + 31595833 = 31595984
283 + 31595701 = 31595984
313 + 31595671 = 31595984
331 + 31595653 = 31595984
373 + 31595611 = 31595984
577 + 31595407 = 31595984
601 + 31595383 = 31595984

Showing the first eight; more decompositions exist.
