Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624366, here are decompositions:

3 + 31624363 = 31624366
17 + 31624349 = 31624366
23 + 31624343 = 31624366
29 + 31624337 = 31624366
83 + 31624283 = 31624366
89 + 31624277 = 31624366
149 + 31624217 = 31624366
239 + 31624127 = 31624366

Showing the first eight; more decompositions exist.
