Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724660, here are decompositions:

11 + 8724649 = 8724660
17 + 8724643 = 8724660
19 + 8724641 = 8724660
29 + 8724631 = 8724660
41 + 8724619 = 8724660
59 + 8724601 = 8724660
71 + 8724589 = 8724660
101 + 8724559 = 8724660

Showing the first eight; more decompositions exist.
