Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624548, here are decompositions:

37 + 31624511 = 31624548
41 + 31624507 = 31624548
71 + 31624477 = 31624548
181 + 31624367 = 31624548
191 + 31624357 = 31624548
199 + 31624349 = 31624548
211 + 31624337 = 31624548
227 + 31624321 = 31624548

Showing the first eight; more decompositions exist.
