Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591926, here are decompositions:

17 + 8591909 = 8591926
113 + 8591813 = 8591926
179 + 8591747 = 8591926
263 + 8591663 = 8591926
293 + 8591633 = 8591926
353 + 8591573 = 8591926
383 + 8591543 = 8591926
419 + 8591507 = 8591926

Showing the first eight; more decompositions exist.
