Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615058, here are decompositions:

19 + 31615039 = 31615058
199 + 31614859 = 31615058
229 + 31614829 = 31615058
271 + 31614787 = 31615058
457 + 31614601 = 31615058
499 + 31614559 = 31615058
829 + 31614229 = 31615058
859 + 31614199 = 31615058

Showing the first eight; more decompositions exist.
