Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591646, here are decompositions:

13 + 8591633 = 8591646
23 + 8591623 = 8591646
29 + 8591617 = 8591646
43 + 8591603 = 8591646
47 + 8591599 = 8591646
53 + 8591593 = 8591646
59 + 8591587 = 8591646
73 + 8591573 = 8591646

Showing the first eight; more decompositions exist.
