Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700866, here are decompositions:

67 + 8700799 = 8700866
73 + 8700793 = 8700866
157 + 8700709 = 8700866
277 + 8700589 = 8700866
337 + 8700529 = 8700866
409 + 8700457 = 8700866
613 + 8700253 = 8700866
673 + 8700193 = 8700866

Showing the first eight; more decompositions exist.
