Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695666, here are decompositions:

3 + 8695663 = 8695666
137 + 8695529 = 8695666
233 + 8695433 = 8695666
293 + 8695373 = 8695666
347 + 8695319 = 8695666
389 + 8695277 = 8695666
443 + 8695223 = 8695666
467 + 8695199 = 8695666

Showing the first eight; more decompositions exist.
