Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641070, here are decompositions:

7 + 8641063 = 8641070
103 + 8640967 = 8641070
181 + 8640889 = 8641070
199 + 8640871 = 8641070
211 + 8640859 = 8641070
271 + 8640799 = 8641070
283 + 8640787 = 8641070
331 + 8640739 = 8641070

Showing the first eight; more decompositions exist.
