Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639618, here are decompositions:

19 + 8639599 = 8639618
67 + 8639551 = 8639618
79 + 8639539 = 8639618
157 + 8639461 = 8639618
271 + 8639347 = 8639618
367 + 8639251 = 8639618
457 + 8639161 = 8639618
487 + 8639131 = 8639618

Showing the first eight; more decompositions exist.
