Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632778, here are decompositions:

19 + 8632759 = 8632778
61 + 8632717 = 8632778
79 + 8632699 = 8632778
157 + 8632621 = 8632778
181 + 8632597 = 8632778
199 + 8632579 = 8632778
367 + 8632411 = 8632778
379 + 8632399 = 8632778

Showing the first eight; more decompositions exist.
