Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624424, here are decompositions:

37 + 31624387 = 31624424
61 + 31624363 = 31624424
67 + 31624357 = 31624424
103 + 31624321 = 31624424
277 + 31624147 = 31624424
283 + 31624141 = 31624424
421 + 31624003 = 31624424
457 + 31623967 = 31624424

Showing the first eight; more decompositions exist.
