Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624622, here are decompositions:

31 + 31624591 = 31624622
193 + 31624429 = 31624622
199 + 31624423 = 31624622
283 + 31624339 = 31624622
619 + 31624003 = 31624622
643 + 31623979 = 31624622
691 + 31623931 = 31624622
919 + 31623703 = 31624622

Showing the first eight; more decompositions exist.
