Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666926, here are decompositions:

179 + 8666747 = 8666926
383 + 8666543 = 8666926
449 + 8666477 = 8666926
467 + 8666459 = 8666926
509 + 8666417 = 8666926
557 + 8666369 = 8666926
599 + 8666327 = 8666926
743 + 8666183 = 8666926

Showing the first eight; more decompositions exist.
