Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666788, here are decompositions:

5 + 8666783 = 8666788
41 + 8666747 = 8666788
107 + 8666681 = 8666788
191 + 8666597 = 8666788
197 + 8666591 = 8666788
269 + 8666519 = 8666788
311 + 8666477 = 8666788
401 + 8666387 = 8666788

Showing the first eight; more decompositions exist.
