Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724686, here are decompositions:

37 + 8724649 = 8724686
43 + 8724643 = 8724686
67 + 8724619 = 8724686
97 + 8724589 = 8724686
127 + 8724559 = 8724686
193 + 8724493 = 8724686
199 + 8724487 = 8724686
367 + 8724319 = 8724686

Showing the first eight; more decompositions exist.
