Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726810, here are decompositions:

7 + 8726803 = 8726810
73 + 8726737 = 8726810
97 + 8726713 = 8726810
139 + 8726671 = 8726810
163 + 8726647 = 8726810
199 + 8726611 = 8726810
223 + 8726587 = 8726810
241 + 8726569 = 8726810

Showing the first eight; more decompositions exist.
