Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717144, here are decompositions:

13 + 8717131 = 8717144
31 + 8717113 = 8717144
103 + 8717041 = 8717144
283 + 8716861 = 8717144
577 + 8716567 = 8717144
613 + 8716531 = 8717144
691 + 8716453 = 8717144
907 + 8716237 = 8717144

Showing the first eight; more decompositions exist.
