Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729124, here are decompositions:

7 + 8729117 = 8729124
17 + 8729107 = 8729124
31 + 8729093 = 8729124
43 + 8729081 = 8729124
67 + 8729057 = 8729124
71 + 8729053 = 8729124
73 + 8729051 = 8729124
137 + 8728987 = 8729124

Showing the first eight; more decompositions exist.
