Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624354, here are decompositions:

5 + 31624349 = 31624354
11 + 31624343 = 31624354
17 + 31624337 = 31624354
23 + 31624331 = 31624354
71 + 31624283 = 31624354
137 + 31624217 = 31624354
227 + 31624127 = 31624354
353 + 31624001 = 31624354

Showing the first eight; more decompositions exist.
