Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677866, here are decompositions:

19 + 8677847 = 8677866
37 + 8677829 = 8677866
103 + 8677763 = 8677866
107 + 8677759 = 8677866
139 + 8677727 = 8677866
313 + 8677553 = 8677866
383 + 8677483 = 8677866
389 + 8677477 = 8677866

Showing the first eight; more decompositions exist.
