Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697786, here are decompositions:

7 + 8697779 = 8697786
17 + 8697769 = 8697786
79 + 8697707 = 8697786
89 + 8697697 = 8697786
103 + 8697683 = 8697786
109 + 8697677 = 8697786
173 + 8697613 = 8697786
179 + 8697607 = 8697786

Showing the first eight; more decompositions exist.
