Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641056, here are decompositions:

79 + 8640977 = 8641056
89 + 8640967 = 8641056
107 + 8640949 = 8641056
167 + 8640889 = 8641056
173 + 8640883 = 8641056
197 + 8640859 = 8641056
233 + 8640823 = 8641056
239 + 8640817 = 8641056

Showing the first eight; more decompositions exist.
