Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726658, here are decompositions:

11 + 8726647 = 8726658
47 + 8726611 = 8726658
71 + 8726587 = 8726658
89 + 8726569 = 8726658
131 + 8726527 = 8726658
137 + 8726521 = 8726658
151 + 8726507 = 8726658
179 + 8726479 = 8726658

Showing the first eight; more decompositions exist.
