Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717140, here are decompositions:

17 + 8717123 = 8717140
23 + 8717117 = 8717140
197 + 8716943 = 8717140
251 + 8716889 = 8717140
431 + 8716709 = 8717140
449 + 8716691 = 8717140
461 + 8716679 = 8717140
479 + 8716661 = 8717140

Showing the first eight; more decompositions exist.
