Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639294, here are decompositions:

3 + 8639291 = 8639294
31 + 8639263 = 8639294
43 + 8639251 = 8639294
67 + 8639227 = 8639294
151 + 8639143 = 8639294
163 + 8639131 = 8639294
283 + 8639011 = 8639294
487 + 8638807 = 8639294

Showing the first eight; more decompositions exist.
