Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717256, here are decompositions:

17 + 8717239 = 8717256
43 + 8717213 = 8717256
137 + 8717119 = 8717256
139 + 8717117 = 8717256
257 + 8716999 = 8717256
313 + 8716943 = 8717256
337 + 8716919 = 8717256
367 + 8716889 = 8717256

Showing the first eight; more decompositions exist.
