Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639354, here are decompositions:

7 + 8639347 = 8639354
103 + 8639251 = 8639354
127 + 8639227 = 8639354
193 + 8639161 = 8639354
211 + 8639143 = 8639354
223 + 8639131 = 8639354
421 + 8638933 = 8639354
463 + 8638891 = 8639354

Showing the first eight; more decompositions exist.
