Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615274, here are decompositions:

37 + 31615237 = 31615274
211 + 31615063 = 31615274
331 + 31614943 = 31615274
421 + 31614853 = 31615274
487 + 31614787 = 31615274
541 + 31614733 = 31615274
571 + 31614703 = 31615274
577 + 31614697 = 31615274

Showing the first eight; more decompositions exist.
