Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649316, here are decompositions:

17 + 8649299 = 8649316
23 + 8649293 = 8649316
89 + 8649227 = 8649316
293 + 8649023 = 8649316
449 + 8648867 = 8649316
479 + 8648837 = 8649316
503 + 8648813 = 8649316
569 + 8648747 = 8649316

Showing the first eight; more decompositions exist.
