Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756866, here are decompositions:

23 + 8756843 = 8756866
29 + 8756837 = 8756866
59 + 8756807 = 8756866
179 + 8756687 = 8756866
197 + 8756669 = 8756866
233 + 8756633 = 8756866
257 + 8756609 = 8756866
347 + 8756519 = 8756866

Showing the first eight; more decompositions exist.
