Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697666, here are decompositions:

53 + 8697613 = 8697666
59 + 8697607 = 8697666
67 + 8697599 = 8697666
79 + 8697587 = 8697666
127 + 8697539 = 8697666
157 + 8697509 = 8697666
163 + 8697503 = 8697666
167 + 8697499 = 8697666

Showing the first eight; more decompositions exist.
