Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729266, here are decompositions:

17 + 8729249 = 8729266
23 + 8729243 = 8729266
47 + 8729219 = 8729266
59 + 8729207 = 8729266
83 + 8729183 = 8729266
149 + 8729117 = 8729266
167 + 8729099 = 8729266
173 + 8729093 = 8729266

Showing the first eight; more decompositions exist.
