Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636560, here are decompositions:

11 + 8636549 = 8636560
17 + 8636543 = 8636560
47 + 8636513 = 8636560
137 + 8636423 = 8636560
173 + 8636387 = 8636560
419 + 8636141 = 8636560
431 + 8636129 = 8636560
467 + 8636093 = 8636560

Showing the first eight; more decompositions exist.
