Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645298, here are decompositions:

5 + 8645293 = 8645298
17 + 8645281 = 8645298
29 + 8645269 = 8645298
31 + 8645267 = 8645298
37 + 8645261 = 8645298
41 + 8645257 = 8645298
59 + 8645239 = 8645298
61 + 8645237 = 8645298

Showing the first eight; more decompositions exist.
