Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624482, here are decompositions:

5 + 31624477 = 31624482
53 + 31624429 = 31624482
59 + 31624423 = 31624482
139 + 31624343 = 31624482
151 + 31624331 = 31624482
199 + 31624283 = 31624482
353 + 31624129 = 31624482
479 + 31624003 = 31624482

Showing the first eight; more decompositions exist.
