Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697648, here are decompositions:

7 + 8697641 = 8697648
41 + 8697607 = 8697648
61 + 8697587 = 8697648
67 + 8697581 = 8697648
97 + 8697551 = 8697648
109 + 8697539 = 8697648
137 + 8697511 = 8697648
139 + 8697509 = 8697648

Showing the first eight; more decompositions exist.
