Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642266, here are decompositions:

29 + 8642237 = 8642266
107 + 8642159 = 8642266
167 + 8642099 = 8642266
233 + 8642033 = 8642266
239 + 8642027 = 8642266
263 + 8642003 = 8642266
317 + 8641949 = 8642266
383 + 8641883 = 8642266

Showing the first eight; more decompositions exist.
