Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724998, here are decompositions:

31 + 8724967 = 8724998
127 + 8724871 = 8724998
151 + 8724847 = 8724998
199 + 8724799 = 8724998
211 + 8724787 = 8724998
277 + 8724721 = 8724998
349 + 8724649 = 8724998
367 + 8724631 = 8724998

Showing the first eight; more decompositions exist.
