Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624456, here are decompositions:

89 + 31624367 = 31624456
107 + 31624349 = 31624456
113 + 31624343 = 31624456
173 + 31624283 = 31624456
179 + 31624277 = 31624456
239 + 31624217 = 31624456
443 + 31624013 = 31624456
467 + 31623989 = 31624456

Showing the first eight; more decompositions exist.
