Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641008, here are decompositions:

31 + 8640977 = 8641008
41 + 8640967 = 8641008
59 + 8640949 = 8641008
97 + 8640911 = 8641008
137 + 8640871 = 8641008
149 + 8640859 = 8641008
191 + 8640817 = 8641008
227 + 8640781 = 8641008

Showing the first eight; more decompositions exist.
