Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729766, here are decompositions:

37 + 8729729 = 8729766
107 + 8729659 = 8729766
137 + 8729629 = 8729766
163 + 8729603 = 8729766
173 + 8729593 = 8729766
223 + 8729543 = 8729766
337 + 8729429 = 8729766
433 + 8729333 = 8729766

Showing the first eight; more decompositions exist.
