Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615364, here are decompositions:

31 + 31615333 = 31615364
43 + 31615321 = 31615364
127 + 31615237 = 31615364
211 + 31615153 = 31615364
421 + 31614943 = 31615364
577 + 31614787 = 31615364
631 + 31614733 = 31615364
661 + 31614703 = 31615364

Showing the first eight; more decompositions exist.
