Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616724, here are decompositions:

17 + 31616707 = 31616724
31 + 31616693 = 31616724
37 + 31616687 = 31616724
47 + 31616677 = 31616724
53 + 31616671 = 31616724
101 + 31616623 = 31616724
163 + 31616561 = 31616724
313 + 31616411 = 31616724

Showing the first eight; more decompositions exist.
