Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630212, here are decompositions:

5 + 8630207 = 8630212
11 + 8630201 = 8630212
53 + 8630159 = 8630212
251 + 8629961 = 8630212
263 + 8629949 = 8630212
389 + 8629823 = 8630212
449 + 8629763 = 8630212
599 + 8629613 = 8630212

Showing the first eight; more decompositions exist.
