Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724662, here are decompositions:

13 + 8724649 = 8724662
19 + 8724643 = 8724662
31 + 8724631 = 8724662
43 + 8724619 = 8724662
61 + 8724601 = 8724662
73 + 8724589 = 8724662
103 + 8724559 = 8724662
151 + 8724511 = 8724662

Showing the first eight; more decompositions exist.
