Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624698, here are decompositions:

37 + 31624661 = 31624698
59 + 31624639 = 31624698
67 + 31624631 = 31624698
71 + 31624627 = 31624698
101 + 31624597 = 31624698
107 + 31624591 = 31624698
139 + 31624559 = 31624698
151 + 31624547 = 31624698

Showing the first eight; more decompositions exist.
