Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645266, here are decompositions:

5 + 8645261 = 8645266
23 + 8645243 = 8645266
29 + 8645237 = 8645266
257 + 8645009 = 8645266
317 + 8644949 = 8645266
347 + 8644919 = 8645266
353 + 8644913 = 8645266
467 + 8644799 = 8645266

Showing the first eight; more decompositions exist.
