Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729230, here are decompositions:

11 + 8729219 = 8729230
23 + 8729207 = 8729230
47 + 8729183 = 8729230
89 + 8729141 = 8729230
113 + 8729117 = 8729230
131 + 8729099 = 8729230
137 + 8729093 = 8729230
149 + 8729081 = 8729230

Showing the first eight; more decompositions exist.
