Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648560, here are decompositions:

3 + 8648557 = 8648560
17 + 8648543 = 8648560
23 + 8648537 = 8648560
29 + 8648531 = 8648560
47 + 8648513 = 8648560
59 + 8648501 = 8648560
101 + 8648459 = 8648560
113 + 8648447 = 8648560

Showing the first eight; more decompositions exist.
