Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717744, here are decompositions:

3 + 8717741 = 8717744
67 + 8717677 = 8717744
181 + 8717563 = 8717744
193 + 8717551 = 8717744
223 + 8717521 = 8717744
421 + 8717323 = 8717744
457 + 8717287 = 8717744
613 + 8717131 = 8717744

Showing the first eight; more decompositions exist.
