Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645998, here are decompositions:

17 + 8645981 = 8645998
71 + 8645927 = 8645998
149 + 8645849 = 8645998
239 + 8645759 = 8645998
269 + 8645729 = 8645998
311 + 8645687 = 8645998
401 + 8645597 = 8645998
419 + 8645579 = 8645998

Showing the first eight; more decompositions exist.
