Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641226, here are decompositions:

79 + 8641147 = 8641226
163 + 8641063 = 8641226
277 + 8640949 = 8641226
337 + 8640889 = 8641226
367 + 8640859 = 8641226
409 + 8640817 = 8641226
439 + 8640787 = 8641226
487 + 8640739 = 8641226

Showing the first eight; more decompositions exist.
