Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642766, here are decompositions:

5 + 8642761 = 8642766
19 + 8642747 = 8642766
43 + 8642723 = 8642766
199 + 8642567 = 8642766
233 + 8642533 = 8642766
257 + 8642509 = 8642766
277 + 8642489 = 8642766
313 + 8642453 = 8642766

Showing the first eight; more decompositions exist.
