Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611560, here are decompositions:

11 + 8611549 = 8611560
29 + 8611531 = 8611560
31 + 8611529 = 8611560
37 + 8611523 = 8611560
59 + 8611501 = 8611560
73 + 8611487 = 8611560
127 + 8611433 = 8611560
137 + 8611423 = 8611560

Showing the first eight; more decompositions exist.
