Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729122, here are decompositions:

5 + 8729117 = 8729122
23 + 8729099 = 8729122
29 + 8729093 = 8729122
41 + 8729081 = 8729122
71 + 8729051 = 8729122
89 + 8729033 = 8729122
179 + 8728943 = 8729122
239 + 8728883 = 8729122

Showing the first eight; more decompositions exist.
