Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705790, here are decompositions:

13 + 8705777 = 8705790
17 + 8705773 = 8705790
31 + 8705759 = 8705790
43 + 8705747 = 8705790
61 + 8705729 = 8705790
101 + 8705689 = 8705790
109 + 8705681 = 8705790
151 + 8705639 = 8705790

Showing the first eight; more decompositions exist.
