Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730528, here are decompositions:

11 + 8730517 = 8730528
17 + 8730511 = 8730528
41 + 8730487 = 8730528
61 + 8730467 = 8730528
151 + 8730377 = 8730528
179 + 8730349 = 8730528
197 + 8730331 = 8730528
241 + 8730287 = 8730528

Showing the first eight; more decompositions exist.
