Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700822, here are decompositions:

5 + 8700817 = 8700822
23 + 8700799 = 8700822
29 + 8700793 = 8700822
71 + 8700751 = 8700822
101 + 8700721 = 8700822
113 + 8700709 = 8700822
173 + 8700649 = 8700822
223 + 8700599 = 8700822

Showing the first eight; more decompositions exist.
