Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666806, here are decompositions:

23 + 8666783 = 8666806
59 + 8666747 = 8666806
179 + 8666627 = 8666806
263 + 8666543 = 8666806
293 + 8666513 = 8666806
347 + 8666459 = 8666806
389 + 8666417 = 8666806
419 + 8666387 = 8666806

Showing the first eight; more decompositions exist.
