Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657926, here are decompositions:

3 + 8657923 = 8657926
23 + 8657903 = 8657926
227 + 8657699 = 8657926
239 + 8657687 = 8657926
293 + 8657633 = 8657926
359 + 8657567 = 8657926
503 + 8657423 = 8657926
569 + 8657357 = 8657926

Showing the first eight; more decompositions exist.
