Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700806, here are decompositions:

7 + 8700799 = 8700806
13 + 8700793 = 8700806
97 + 8700709 = 8700806
109 + 8700697 = 8700806
157 + 8700649 = 8700806
277 + 8700529 = 8700806
349 + 8700457 = 8700806
523 + 8700283 = 8700806

Showing the first eight; more decompositions exist.
