Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624352, here are decompositions:

3 + 31624349 = 31624352
13 + 31624339 = 31624352
31 + 31624321 = 31624352
211 + 31624141 = 31624352
223 + 31624129 = 31624352
283 + 31624069 = 31624352
349 + 31624003 = 31624352
373 + 31623979 = 31624352

Showing the first eight; more decompositions exist.
