Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666746, here are decompositions:

149 + 8666597 = 8666746
227 + 8666519 = 8666746
233 + 8666513 = 8666746
269 + 8666477 = 8666746
353 + 8666393 = 8666746
359 + 8666387 = 8666746
419 + 8666327 = 8666746
509 + 8666237 = 8666746

Showing the first eight; more decompositions exist.
