Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624858, here are decompositions:

29 + 31624829 = 31624858
59 + 31624799 = 31624858
197 + 31624661 = 31624858
227 + 31624631 = 31624858
311 + 31624547 = 31624858
347 + 31624511 = 31624858
401 + 31624457 = 31624858
491 + 31624367 = 31624858

Showing the first eight; more decompositions exist.
