Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666536, here are decompositions:

3 + 8666533 = 8666536
17 + 8666519 = 8666536
23 + 8666513 = 8666536
59 + 8666477 = 8666536
149 + 8666387 = 8666536
167 + 8666369 = 8666536
317 + 8666219 = 8666536
353 + 8666183 = 8666536

Showing the first eight; more decompositions exist.
