Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624296, here are decompositions:

13 + 31624283 = 31624296
19 + 31624277 = 31624296
79 + 31624217 = 31624296
149 + 31624147 = 31624296
167 + 31624129 = 31624296
227 + 31624069 = 31624296
283 + 31624013 = 31624296
293 + 31624003 = 31624296

Showing the first eight; more decompositions exist.
