Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645284, here are decompositions:

3 + 8645281 = 8645284
17 + 8645267 = 8645284
23 + 8645261 = 8645284
41 + 8645243 = 8645284
47 + 8645237 = 8645284
293 + 8644991 = 8645284
503 + 8644781 = 8645284
677 + 8644607 = 8645284

Showing the first eight; more decompositions exist.
