Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729746, here are decompositions:

17 + 8729729 = 8729746
29 + 8729717 = 8729746
317 + 8729429 = 8729746
419 + 8729327 = 8729746
503 + 8729243 = 8729746
563 + 8729183 = 8729746
647 + 8729099 = 8729746
653 + 8729093 = 8729746

Showing the first eight; more decompositions exist.
