Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617046, here are decompositions:

17 + 31617029 = 31617046
23 + 31617023 = 31617046
47 + 31616999 = 31617046
59 + 31616987 = 31617046
113 + 31616933 = 31617046
317 + 31616729 = 31617046
353 + 31616693 = 31617046
359 + 31616687 = 31617046

Showing the first eight; more decompositions exist.
