Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729118, here are decompositions:

11 + 8729107 = 8729118
19 + 8729099 = 8729118
37 + 8729081 = 8729118
59 + 8729059 = 8729118
61 + 8729057 = 8729118
67 + 8729051 = 8729118
131 + 8728987 = 8729118
149 + 8728969 = 8729118

Showing the first eight; more decompositions exist.
