Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624564, here are decompositions:

5 + 31624559 = 31624564
17 + 31624547 = 31624564
53 + 31624511 = 31624564
107 + 31624457 = 31624564
197 + 31624367 = 31624564
227 + 31624337 = 31624564
233 + 31624331 = 31624564
281 + 31624283 = 31624564

Showing the first eight; more decompositions exist.
