Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591998, here are decompositions:

71 + 8591927 = 8591998
89 + 8591909 = 8591998
167 + 8591831 = 8591998
227 + 8591771 = 8591998
251 + 8591747 = 8591998
281 + 8591717 = 8591998
449 + 8591549 = 8591998
479 + 8591519 = 8591998

Showing the first eight; more decompositions exist.
