Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729510, here are decompositions:

19 + 8729491 = 8729510
43 + 8729467 = 8729510
109 + 8729401 = 8729510
193 + 8729317 = 8729510
271 + 8729239 = 8729510
331 + 8729179 = 8729510
337 + 8729173 = 8729510
379 + 8729131 = 8729510

Showing the first eight; more decompositions exist.
