Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671284, here are decompositions:

53 + 8671231 = 8671284
107 + 8671177 = 8671284
137 + 8671147 = 8671284
151 + 8671133 = 8671284
157 + 8671127 = 8671284
227 + 8671057 = 8671284
233 + 8671051 = 8671284
277 + 8671007 = 8671284

Showing the first eight; more decompositions exist.
