Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666632, here are decompositions:

5 + 8666627 = 8666632
41 + 8666591 = 8666632
89 + 8666543 = 8666632
113 + 8666519 = 8666632
131 + 8666501 = 8666632
173 + 8666459 = 8666632
239 + 8666393 = 8666632
251 + 8666381 = 8666632

Showing the first eight; more decompositions exist.
