Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615094, here are decompositions:

31 + 31615063 = 31615094
151 + 31614943 = 31615094
241 + 31614853 = 31615094
307 + 31614787 = 31615094
397 + 31614697 = 31615094
463 + 31614631 = 31615094
547 + 31614547 = 31615094
571 + 31614523 = 31615094

Showing the first eight; more decompositions exist.
