Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624606, here are decompositions:

47 + 31624559 = 31624606
59 + 31624547 = 31624606
149 + 31624457 = 31624606
239 + 31624367 = 31624606
257 + 31624349 = 31624606
263 + 31624343 = 31624606
269 + 31624337 = 31624606
389 + 31624217 = 31624606

Showing the first eight; more decompositions exist.
