Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624516, here are decompositions:

5 + 31624511 = 31624516
59 + 31624457 = 31624516
149 + 31624367 = 31624516
167 + 31624349 = 31624516
173 + 31624343 = 31624516
179 + 31624337 = 31624516
233 + 31624283 = 31624516
239 + 31624277 = 31624516

Showing the first eight; more decompositions exist.
