Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697790, here are decompositions:

11 + 8697779 = 8697790
83 + 8697707 = 8697790
107 + 8697683 = 8697790
113 + 8697677 = 8697790
149 + 8697641 = 8697790
191 + 8697599 = 8697790
239 + 8697551 = 8697790
251 + 8697539 = 8697790

Showing the first eight; more decompositions exist.
