Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700660, here are decompositions:

11 + 8700649 = 8700660
61 + 8700599 = 8700660
71 + 8700589 = 8700660
79 + 8700581 = 8700660
97 + 8700563 = 8700660
113 + 8700547 = 8700660
131 + 8700529 = 8700660
139 + 8700521 = 8700660

Showing the first eight; more decompositions exist.
