Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645958, here are decompositions:

17 + 8645941 = 8645958
31 + 8645927 = 8645958
59 + 8645899 = 8645958
71 + 8645887 = 8645958
109 + 8645849 = 8645958
197 + 8645761 = 8645958
199 + 8645759 = 8645958
229 + 8645729 = 8645958

Showing the first eight; more decompositions exist.
