Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616732, here are decompositions:

3 + 31616729 = 31616732
61 + 31616671 = 31616732
109 + 31616623 = 31616732
163 + 31616569 = 31616732
193 + 31616539 = 31616732
211 + 31616521 = 31616732
223 + 31616509 = 31616732
313 + 31616419 = 31616732

Showing the first eight; more decompositions exist.
