Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614668, here are decompositions:

37 + 31614631 = 31614668
67 + 31614601 = 31614668
109 + 31614559 = 31614668
439 + 31614229 = 31614668
457 + 31614211 = 31614668
487 + 31614181 = 31614668
571 + 31614097 = 31614668
577 + 31614091 = 31614668

Showing the first eight; more decompositions exist.
