Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615064, here are decompositions:

3 + 31615061 = 31615064
211 + 31614853 = 31615064
277 + 31614787 = 31615064
331 + 31614733 = 31615064
367 + 31614697 = 31615064
421 + 31614643 = 31615064
433 + 31614631 = 31615064
463 + 31614601 = 31615064

Showing the first eight; more decompositions exist.
