Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639426, here are decompositions:

13 + 8639413 = 8639426
79 + 8639347 = 8639426
127 + 8639299 = 8639426
163 + 8639263 = 8639426
199 + 8639227 = 8639426
277 + 8639149 = 8639426
283 + 8639143 = 8639426
307 + 8639119 = 8639426

Showing the first eight; more decompositions exist.
