Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697638, here are decompositions:

31 + 8697607 = 8697638
127 + 8697511 = 8697638
139 + 8697499 = 8697638
337 + 8697301 = 8697638
541 + 8697097 = 8697638
577 + 8697061 = 8697638
601 + 8697037 = 8697638
661 + 8696977 = 8697638

Showing the first eight; more decompositions exist.
