Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616536, here are decompositions:

113 + 31616423 = 31616536
167 + 31616369 = 31616536
173 + 31616363 = 31616536
197 + 31616339 = 31616536
239 + 31616297 = 31616536
317 + 31616219 = 31616536
353 + 31616183 = 31616536
467 + 31616069 = 31616536

Showing the first eight; more decompositions exist.
