Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591626, here are decompositions:

3 + 8591623 = 8591626
23 + 8591603 = 8591626
53 + 8591573 = 8591626
83 + 8591543 = 8591626
107 + 8591519 = 8591626
257 + 8591369 = 8591626
389 + 8591237 = 8591626
443 + 8591183 = 8591626

Showing the first eight; more decompositions exist.
