Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616566, here are decompositions:

5 + 31616561 = 31616566
173 + 31616393 = 31616566
197 + 31616369 = 31616566
227 + 31616339 = 31616566
239 + 31616327 = 31616566
269 + 31616297 = 31616566
347 + 31616219 = 31616566
383 + 31616183 = 31616566

Showing the first eight; more decompositions exist.
