Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636778, here are decompositions:

19 + 8636759 = 8636778
37 + 8636741 = 8636778
41 + 8636737 = 8636778
89 + 8636689 = 8636778
107 + 8636671 = 8636778
131 + 8636647 = 8636778
151 + 8636627 = 8636778
179 + 8636599 = 8636778

Showing the first eight; more decompositions exist.
