Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615004, here are decompositions:

61 + 31614943 = 31615004
151 + 31614853 = 31615004
271 + 31614733 = 31615004
307 + 31614697 = 31615004
373 + 31614631 = 31615004
457 + 31614547 = 31615004
661 + 31614343 = 31615004
727 + 31614277 = 31615004

Showing the first eight; more decompositions exist.
