Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624612, here are decompositions:

53 + 31624559 = 31624612
101 + 31624511 = 31624612
263 + 31624349 = 31624612
269 + 31624343 = 31624612
281 + 31624331 = 31624612
599 + 31624013 = 31624612
641 + 31623971 = 31624612
653 + 31623959 = 31624612

Showing the first eight; more decompositions exist.
