Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624368, here are decompositions:

5 + 31624363 = 31624368
11 + 31624357 = 31624368
19 + 31624349 = 31624368
29 + 31624339 = 31624368
31 + 31624337 = 31624368
37 + 31624331 = 31624368
47 + 31624321 = 31624368
151 + 31624217 = 31624368

Showing the first eight; more decompositions exist.
