Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591648, here are decompositions:

31 + 8591617 = 8591648
61 + 8591587 = 8591648
181 + 8591467 = 8591648
199 + 8591449 = 8591648
229 + 8591419 = 8591648
271 + 8591377 = 8591648
337 + 8591311 = 8591648
349 + 8591299 = 8591648

Showing the first eight; more decompositions exist.
