Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729836, here are decompositions:

107 + 8729729 = 8729836
233 + 8729603 = 8729836
293 + 8729543 = 8729836
503 + 8729333 = 8729836
509 + 8729327 = 8729836
587 + 8729249 = 8729836
593 + 8729243 = 8729836
617 + 8729219 = 8729836

Showing the first eight; more decompositions exist.
