Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641026, here are decompositions:

19 + 8641007 = 8641026
59 + 8640967 = 8641026
137 + 8640889 = 8641026
139 + 8640887 = 8641026
167 + 8640859 = 8641026
227 + 8640799 = 8641026
239 + 8640787 = 8641026
293 + 8640733 = 8641026

Showing the first eight; more decompositions exist.
