Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632878, here are decompositions:

47 + 8632831 = 8632878
61 + 8632817 = 8632878
101 + 8632777 = 8632878
151 + 8632727 = 8632878
179 + 8632699 = 8632878
211 + 8632667 = 8632878
229 + 8632649 = 8632878
257 + 8632621 = 8632878

Showing the first eight; more decompositions exist.
