Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639366, here are decompositions:

3 + 8639363 = 8639366
19 + 8639347 = 8639366
67 + 8639299 = 8639366
103 + 8639263 = 8639366
139 + 8639227 = 8639366
223 + 8639143 = 8639366
277 + 8639089 = 8639366
367 + 8638999 = 8639366

Showing the first eight; more decompositions exist.
