Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624636, here are decompositions:

5 + 31624631 = 31624636
23 + 31624613 = 31624636
89 + 31624547 = 31624636
179 + 31624457 = 31624636
269 + 31624367 = 31624636
293 + 31624343 = 31624636
353 + 31624283 = 31624636
359 + 31624277 = 31624636

Showing the first eight; more decompositions exist.
