Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724746, here are decompositions:

7 + 8724739 = 8724746
97 + 8724649 = 8724746
103 + 8724643 = 8724746
127 + 8724619 = 8724746
157 + 8724589 = 8724746
463 + 8724283 = 8724746
487 + 8724259 = 8724746
523 + 8724223 = 8724746

Showing the first eight; more decompositions exist.
