Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724732, here are decompositions:

11 + 8724721 = 8724732
13 + 8724719 = 8724732
19 + 8724713 = 8724732
83 + 8724649 = 8724732
89 + 8724643 = 8724732
101 + 8724631 = 8724732
113 + 8724619 = 8724732
131 + 8724601 = 8724732

Showing the first eight; more decompositions exist.
