Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624610, here are decompositions:

13 + 31624597 = 31624610
19 + 31624591 = 31624610
103 + 31624507 = 31624610
181 + 31624429 = 31624610
223 + 31624387 = 31624610
271 + 31624339 = 31624610
463 + 31624147 = 31624610
541 + 31624069 = 31624610

Showing the first eight; more decompositions exist.
