Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639450, here are decompositions:

7 + 8639443 = 8639450
37 + 8639413 = 8639450
103 + 8639347 = 8639450
151 + 8639299 = 8639450
199 + 8639251 = 8639450
223 + 8639227 = 8639450
307 + 8639143 = 8639450
331 + 8639119 = 8639450

Showing the first eight; more decompositions exist.
