Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729306, here are decompositions:

67 + 8729239 = 8729306
127 + 8729179 = 8729306
199 + 8729107 = 8729306
337 + 8728969 = 8729306
379 + 8728927 = 8729306
409 + 8728897 = 8729306
457 + 8728849 = 8729306
499 + 8728807 = 8729306

Showing the first eight; more decompositions exist.
