Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724818, here are decompositions:

19 + 8724799 = 8724818
31 + 8724787 = 8724818
79 + 8724739 = 8724818
97 + 8724721 = 8724818
199 + 8724619 = 8724818
229 + 8724589 = 8724818
307 + 8724511 = 8724818
331 + 8724487 = 8724818

Showing the first eight; more decompositions exist.
