Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616746, here are decompositions:

17 + 31616729 = 31616746
53 + 31616693 = 31616746
59 + 31616687 = 31616746
167 + 31616579 = 31616746
353 + 31616393 = 31616746
383 + 31616363 = 31616746
419 + 31616327 = 31616746
449 + 31616297 = 31616746

Showing the first eight; more decompositions exist.
