Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700810, here are decompositions:

11 + 8700799 = 8700810
17 + 8700793 = 8700810
37 + 8700773 = 8700810
43 + 8700767 = 8700810
59 + 8700751 = 8700810
89 + 8700721 = 8700810
101 + 8700709 = 8700810
113 + 8700697 = 8700810

Showing the first eight; more decompositions exist.
