Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697690, here are decompositions:

7 + 8697683 = 8697690
13 + 8697677 = 8697690
83 + 8697607 = 8697690
103 + 8697587 = 8697690
109 + 8697581 = 8697690
139 + 8697551 = 8697690
151 + 8697539 = 8697690
179 + 8697511 = 8697690

Showing the first eight; more decompositions exist.
