Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717646, here are decompositions:

13 + 8717633 = 8717646
23 + 8717623 = 8717646
83 + 8717563 = 8717646
89 + 8717557 = 8717646
137 + 8717509 = 8717646
257 + 8717389 = 8717646
293 + 8717353 = 8717646
317 + 8717329 = 8717646

Showing the first eight; more decompositions exist.
