Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729146, here are decompositions:

5 + 8729141 = 8729146
29 + 8729117 = 8729146
47 + 8729099 = 8729146
53 + 8729093 = 8729146
89 + 8729057 = 8729146
113 + 8729033 = 8729146
263 + 8728883 = 8729146
359 + 8728787 = 8729146

Showing the first eight; more decompositions exist.
