Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616682, here are decompositions:

5 + 31616677 = 31616682
11 + 31616671 = 31616682
59 + 31616623 = 31616682
79 + 31616603 = 31616682
103 + 31616579 = 31616682
113 + 31616569 = 31616682
173 + 31616509 = 31616682
263 + 31616419 = 31616682

Showing the first eight; more decompositions exist.
