Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686788, here are decompositions:

59 + 8686729 = 8686788
67 + 8686721 = 8686788
101 + 8686687 = 8686788
109 + 8686679 = 8686788
127 + 8686661 = 8686788
137 + 8686651 = 8686788
199 + 8686589 = 8686788
317 + 8686471 = 8686788

Showing the first eight; more decompositions exist.
