Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615046, here are decompositions:

7 + 31615039 = 31615046
103 + 31614943 = 31615046
157 + 31614889 = 31615046
193 + 31614853 = 31615046
277 + 31614769 = 31615046
313 + 31614733 = 31615046
349 + 31614697 = 31615046
487 + 31614559 = 31615046

Showing the first eight; more decompositions exist.
