Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677770, here are decompositions:

7 + 8677763 = 8677770
11 + 8677759 = 8677770
43 + 8677727 = 8677770
47 + 8677723 = 8677770
89 + 8677681 = 8677770
107 + 8677663 = 8677770
163 + 8677607 = 8677770
193 + 8677577 = 8677770

Showing the first eight; more decompositions exist.
