Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726628, here are decompositions:

17 + 8726611 = 8726628
41 + 8726587 = 8726628
59 + 8726569 = 8726628
101 + 8726527 = 8726628
107 + 8726521 = 8726628
149 + 8726479 = 8726628
167 + 8726461 = 8726628
179 + 8726449 = 8726628

Showing the first eight; more decompositions exist.
