Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616636, here are decompositions:

13 + 31616623 = 31616636
67 + 31616569 = 31616636
97 + 31616539 = 31616636
127 + 31616509 = 31616636
157 + 31616479 = 31616636
277 + 31616359 = 31616636
349 + 31616287 = 31616636
379 + 31616257 = 31616636

Showing the first eight; more decompositions exist.
