Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591798, here are decompositions:

109 + 8591689 = 8591798
181 + 8591617 = 8591798
199 + 8591599 = 8591798
211 + 8591587 = 8591798
331 + 8591467 = 8591798
349 + 8591449 = 8591798
367 + 8591431 = 8591798
379 + 8591419 = 8591798

Showing the first eight; more decompositions exist.
