Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724648, here are decompositions:

5 + 8724643 = 8724648
7 + 8724641 = 8724648
17 + 8724631 = 8724648
29 + 8724619 = 8724648
47 + 8724601 = 8724648
59 + 8724589 = 8724648
89 + 8724559 = 8724648
137 + 8724511 = 8724648

Showing the first eight; more decompositions exist.
