Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597998, here are decompositions:

5 + 8597993 = 8597998
29 + 8597969 = 8597998
239 + 8597759 = 8597998
347 + 8597651 = 8597998
359 + 8597639 = 8597998
467 + 8597531 = 8597998
659 + 8597339 = 8597998
677 + 8597321 = 8597998

Showing the first eight; more decompositions exist.
