Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717740, here are decompositions:

23 + 8717717 = 8717740
107 + 8717633 = 8717740
149 + 8717591 = 8717740
347 + 8717393 = 8717740
467 + 8717273 = 8717740
569 + 8717171 = 8717740
617 + 8717123 = 8717740
719 + 8717021 = 8717740

Showing the first eight; more decompositions exist.
