Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616616, here are decompositions:

13 + 31616603 = 31616616
37 + 31616579 = 31616616
47 + 31616569 = 31616616
107 + 31616509 = 31616616
137 + 31616479 = 31616616
193 + 31616423 = 31616616
197 + 31616419 = 31616616
223 + 31616393 = 31616616

Showing the first eight; more decompositions exist.
