Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654686, here are decompositions:

23 + 8654663 = 8654686
107 + 8654579 = 8654686
113 + 8654573 = 8654686
197 + 8654489 = 8654686
233 + 8654453 = 8654686
239 + 8654447 = 8654686
347 + 8654339 = 8654686
353 + 8654333 = 8654686

Showing the first eight; more decompositions exist.
