Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614638, here are decompositions:

7 + 31614631 = 31614638
37 + 31614601 = 31614638
79 + 31614559 = 31614638
409 + 31614229 = 31614638
421 + 31614217 = 31614638
439 + 31614199 = 31614638
457 + 31614181 = 31614638
541 + 31614097 = 31614638

Showing the first eight; more decompositions exist.
