Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697664, here are decompositions:

23 + 8697641 = 8697664
83 + 8697581 = 8697664
113 + 8697551 = 8697664
257 + 8697407 = 8697664
401 + 8697263 = 8697664
431 + 8697233 = 8697664
557 + 8697107 = 8697664
761 + 8696903 = 8697664

Showing the first eight; more decompositions exist.
