Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624046, here are decompositions:

43 + 31624003 = 31624046
67 + 31623979 = 31624046
79 + 31623967 = 31624046
229 + 31623817 = 31624046
379 + 31623667 = 31624046
439 + 31623607 = 31624046
457 + 31623589 = 31624046
523 + 31623523 = 31624046

Showing the first eight; more decompositions exist.
