Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624922, here are decompositions:

61 + 31624861 = 31624922
73 + 31624849 = 31624922
139 + 31624783 = 31624922
181 + 31624741 = 31624922
223 + 31624699 = 31624922
283 + 31624639 = 31624922
331 + 31624591 = 31624922
499 + 31624423 = 31624922

Showing the first eight; more decompositions exist.
