Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724822, here are decompositions:

19 + 8724803 = 8724822
23 + 8724799 = 8724822
83 + 8724739 = 8724822
101 + 8724721 = 8724822
103 + 8724719 = 8724822
109 + 8724713 = 8724822
173 + 8724649 = 8724822
179 + 8724643 = 8724822

Showing the first eight; more decompositions exist.
