Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729112, here are decompositions:

5 + 8729107 = 8729112
13 + 8729099 = 8729112
19 + 8729093 = 8729112
31 + 8729081 = 8729112
53 + 8729059 = 8729112
59 + 8729053 = 8729112
61 + 8729051 = 8729112
79 + 8729033 = 8729112

Showing the first eight; more decompositions exist.
