Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639126, here are decompositions:

3 + 8639123 = 8639126
7 + 8639119 = 8639126
19 + 8639107 = 8639126
37 + 8639089 = 8639126
127 + 8638999 = 8639126
193 + 8638933 = 8639126
277 + 8638849 = 8639126
283 + 8638843 = 8639126

Showing the first eight; more decompositions exist.
