Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729506, here are decompositions:

173 + 8729333 = 8729506
179 + 8729327 = 8729506
197 + 8729309 = 8729506
257 + 8729249 = 8729506
263 + 8729243 = 8729506
389 + 8729117 = 8729506
449 + 8729057 = 8729506
563 + 8728943 = 8729506

Showing the first eight; more decompositions exist.
