Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700918, here are decompositions:

7 + 8700911 = 8700918
47 + 8700871 = 8700918
101 + 8700817 = 8700918
151 + 8700767 = 8700918
167 + 8700751 = 8700918
197 + 8700721 = 8700918
269 + 8700649 = 8700918
337 + 8700581 = 8700918

Showing the first eight; more decompositions exist.
