Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657998, here are decompositions:

29 + 8657969 = 8657998
71 + 8657927 = 8657998
149 + 8657849 = 8657998
197 + 8657801 = 8657998
227 + 8657771 = 8657998
311 + 8657687 = 8657998
317 + 8657681 = 8657998
347 + 8657651 = 8657998

Showing the first eight; more decompositions exist.
