Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729574, here are decompositions:

11 + 8729563 = 8729574
17 + 8729557 = 8729574
31 + 8729543 = 8729574
83 + 8729491 = 8729574
107 + 8729467 = 8729574
163 + 8729411 = 8729574
173 + 8729401 = 8729574
241 + 8729333 = 8729574

Showing the first eight; more decompositions exist.
