Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724816, here are decompositions:

13 + 8724803 = 8724816
17 + 8724799 = 8724816
29 + 8724787 = 8724816
97 + 8724719 = 8724816
103 + 8724713 = 8724816
167 + 8724649 = 8724816
173 + 8724643 = 8724816
197 + 8724619 = 8724816

Showing the first eight; more decompositions exist.
