Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726660, here are decompositions:

13 + 8726647 = 8726660
73 + 8726587 = 8726660
127 + 8726533 = 8726660
139 + 8726521 = 8726660
181 + 8726479 = 8726660
193 + 8726467 = 8726660
199 + 8726461 = 8726660
211 + 8726449 = 8726660

Showing the first eight; more decompositions exist.
