Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648266, here are decompositions:

167 + 8648099 = 8648266
173 + 8648093 = 8648266
233 + 8648033 = 8648266
269 + 8647997 = 8648266
317 + 8647949 = 8648266
353 + 8647913 = 8648266
443 + 8647823 = 8648266
449 + 8647817 = 8648266

Showing the first eight; more decompositions exist.
