Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634644, here are decompositions:

127 + 8634517 = 8634644
163 + 8634481 = 8634644
223 + 8634421 = 8634644
433 + 8634211 = 8634644
661 + 8633983 = 8634644
673 + 8633971 = 8634644
751 + 8633893 = 8634644
787 + 8633857 = 8634644

Showing the first eight; more decompositions exist.
