Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616966, here are decompositions:

37 + 31616929 = 31616966
79 + 31616887 = 31616966
109 + 31616857 = 31616966
127 + 31616839 = 31616966
193 + 31616773 = 31616966
397 + 31616569 = 31616966
457 + 31616509 = 31616966
487 + 31616479 = 31616966

Showing the first eight; more decompositions exist.
