Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724842, here are decompositions:

43 + 8724799 = 8724842
103 + 8724739 = 8724842
193 + 8724649 = 8724842
199 + 8724643 = 8724842
211 + 8724631 = 8724842
223 + 8724619 = 8724842
241 + 8724601 = 8724842
283 + 8724559 = 8724842

Showing the first eight; more decompositions exist.
