Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616604, here are decompositions:

43 + 31616561 = 31616604
83 + 31616521 = 31616604
181 + 31616423 = 31616604
193 + 31616411 = 31616604
211 + 31616393 = 31616604
223 + 31616381 = 31616604
241 + 31616363 = 31616604
277 + 31616327 = 31616604

Showing the first eight; more decompositions exist.
