Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607642, here are decompositions:

5 + 8607637 = 8607642
11 + 8607631 = 8607642
13 + 8607629 = 8607642
41 + 8607601 = 8607642
59 + 8607583 = 8607642
79 + 8607563 = 8607642
103 + 8607539 = 8607642
163 + 8607479 = 8607642

Showing the first eight; more decompositions exist.
