Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717158, here are decompositions:

41 + 8717117 = 8717158
137 + 8717021 = 8717158
239 + 8716919 = 8717158
269 + 8716889 = 8717158
389 + 8716769 = 8717158
431 + 8716727 = 8717158
449 + 8716709 = 8717158
467 + 8716691 = 8717158

Showing the first eight; more decompositions exist.
