Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617998, here are decompositions:

5 + 8617993 = 8617998
7 + 8617991 = 8617998
71 + 8617927 = 8617998
127 + 8617871 = 8617998
199 + 8617799 = 8617998
211 + 8617787 = 8617998
229 + 8617769 = 8617998
317 + 8617681 = 8617998

Showing the first eight; more decompositions exist.
