Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624834, here are decompositions:

5 + 31624829 = 31624834
53 + 31624781 = 31624834
71 + 31624763 = 31624834
173 + 31624661 = 31624834
191 + 31624643 = 31624834
467 + 31624367 = 31624834
491 + 31624343 = 31624834
503 + 31624331 = 31624834

Showing the first eight; more decompositions exist.
