Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591598, here are decompositions:

5 + 8591593 = 8591598
11 + 8591587 = 8591598
79 + 8591519 = 8591598
97 + 8591501 = 8591598
131 + 8591467 = 8591598
149 + 8591449 = 8591598
157 + 8591441 = 8591598
167 + 8591431 = 8591598

Showing the first eight; more decompositions exist.
