Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738778, here are decompositions:

11 + 8738767 = 8738778
19 + 8738759 = 8738778
67 + 8738711 = 8738778
71 + 8738707 = 8738778
107 + 8738671 = 8738778
137 + 8738641 = 8738778
197 + 8738581 = 8738778
199 + 8738579 = 8738778

Showing the first eight; more decompositions exist.
