Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729630, here are decompositions:

37 + 8729593 = 8729630
67 + 8729563 = 8729630
73 + 8729557 = 8729630
139 + 8729491 = 8729630
163 + 8729467 = 8729630
229 + 8729401 = 8729630
241 + 8729389 = 8729630
307 + 8729323 = 8729630

Showing the first eight; more decompositions exist.
