Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686790, here are decompositions:

61 + 8686729 = 8686790
103 + 8686687 = 8686790
139 + 8686651 = 8686790
223 + 8686567 = 8686790
331 + 8686459 = 8686790
421 + 8686369 = 8686790
499 + 8686291 = 8686790
577 + 8686213 = 8686790

Showing the first eight; more decompositions exist.
