Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661790, here are decompositions:

23 + 8661767 = 8661790
47 + 8661743 = 8661790
83 + 8661707 = 8661790
101 + 8661689 = 8661790
107 + 8661683 = 8661790
149 + 8661641 = 8661790
167 + 8661623 = 8661790
233 + 8661557 = 8661790

Showing the first eight; more decompositions exist.
