Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641038, here are decompositions:

31 + 8641007 = 8641038
61 + 8640977 = 8641038
71 + 8640967 = 8641038
89 + 8640949 = 8641038
127 + 8640911 = 8641038
149 + 8640889 = 8641038
151 + 8640887 = 8641038
167 + 8640871 = 8641038

Showing the first eight; more decompositions exist.
