Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624396, here are decompositions:

29 + 31624367 = 31624396
47 + 31624349 = 31624396
53 + 31624343 = 31624396
59 + 31624337 = 31624396
113 + 31624283 = 31624396
179 + 31624217 = 31624396
269 + 31624127 = 31624396
383 + 31624013 = 31624396

Showing the first eight; more decompositions exist.
