Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618766, here are decompositions:

7 + 8618759 = 8618766
17 + 8618749 = 8618766
19 + 8618747 = 8618766
29 + 8618737 = 8618766
67 + 8618699 = 8618766
83 + 8618683 = 8618766
127 + 8618639 = 8618766
173 + 8618593 = 8618766

Showing the first eight; more decompositions exist.
