Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640564, here are decompositions:

5 + 8640559 = 8640564
11 + 8640553 = 8640564
17 + 8640547 = 8640564
61 + 8640503 = 8640564
71 + 8640493 = 8640564
83 + 8640481 = 8640564
113 + 8640451 = 8640564
137 + 8640427 = 8640564

Showing the first eight; more decompositions exist.
