Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729316, here are decompositions:

7 + 8729309 = 8729316
67 + 8729249 = 8729316
73 + 8729243 = 8729316
97 + 8729219 = 8729316
109 + 8729207 = 8729316
137 + 8729179 = 8729316
199 + 8729117 = 8729316
223 + 8729093 = 8729316

Showing the first eight; more decompositions exist.
