Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638794, here are decompositions:

61 + 8638733 = 8638794
67 + 8638727 = 8638794
97 + 8638697 = 8638794
103 + 8638691 = 8638794
107 + 8638687 = 8638794
167 + 8638627 = 8638794
173 + 8638621 = 8638794
211 + 8638583 = 8638794

Showing the first eight; more decompositions exist.
