Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724918, here are decompositions:

47 + 8724871 = 8724918
71 + 8724847 = 8724918
131 + 8724787 = 8724918
179 + 8724739 = 8724918
197 + 8724721 = 8724918
199 + 8724719 = 8724918
269 + 8724649 = 8724918
277 + 8724641 = 8724918

Showing the first eight; more decompositions exist.
