Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624598, here are decompositions:

7 + 31624591 = 31624598
211 + 31624387 = 31624598
241 + 31624357 = 31624598
277 + 31624321 = 31624598
457 + 31624141 = 31624598
619 + 31623979 = 31624598
631 + 31623967 = 31624598
877 + 31623721 = 31624598

Showing the first eight; more decompositions exist.
