Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666626, here are decompositions:

29 + 8666597 = 8666626
83 + 8666543 = 8666626
107 + 8666519 = 8666626
113 + 8666513 = 8666626
149 + 8666477 = 8666626
167 + 8666459 = 8666626
233 + 8666393 = 8666626
239 + 8666387 = 8666626

Showing the first eight; more decompositions exist.
