Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616356, here are decompositions:

17 + 31616339 = 31616356
29 + 31616327 = 31616356
59 + 31616297 = 31616356
137 + 31616219 = 31616356
173 + 31616183 = 31616356
227 + 31616129 = 31616356
347 + 31616009 = 31616356
383 + 31615973 = 31616356

Showing the first eight; more decompositions exist.
