Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616694, here are decompositions:

7 + 31616687 = 31616694
17 + 31616677 = 31616694
23 + 31616671 = 31616694
47 + 31616647 = 31616694
71 + 31616623 = 31616694
173 + 31616521 = 31616694
271 + 31616423 = 31616694
283 + 31616411 = 31616694

Showing the first eight; more decompositions exist.
