Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616766, here are decompositions:

17 + 31616749 = 31616766
19 + 31616747 = 31616766
37 + 31616729 = 31616766
59 + 31616707 = 31616766
73 + 31616693 = 31616766
79 + 31616687 = 31616766
89 + 31616677 = 31616766
163 + 31616603 = 31616766

Showing the first eight; more decompositions exist.
