Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624514, here are decompositions:

3 + 31624511 = 31624514
7 + 31624507 = 31624514
37 + 31624477 = 31624514
127 + 31624387 = 31624514
151 + 31624363 = 31624514
157 + 31624357 = 31624514
193 + 31624321 = 31624514
367 + 31624147 = 31624514

Showing the first eight; more decompositions exist.
