Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672418, here are decompositions:

11 + 8672407 = 8672418
31 + 8672387 = 8672418
37 + 8672381 = 8672418
71 + 8672347 = 8672418
151 + 8672267 = 8672418
179 + 8672239 = 8672418
211 + 8672207 = 8672418
241 + 8672177 = 8672418

Showing the first eight; more decompositions exist.
