Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666716, here are decompositions:

5 + 8666711 = 8666716
89 + 8666627 = 8666716
173 + 8666543 = 8666716
197 + 8666519 = 8666716
239 + 8666477 = 8666716
257 + 8666459 = 8666716
347 + 8666369 = 8666716
389 + 8666327 = 8666716

Showing the first eight; more decompositions exist.
