Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641896, here are decompositions:

5 + 8641891 = 8641896
13 + 8641883 = 8641896
23 + 8641873 = 8641896
79 + 8641817 = 8641896
89 + 8641807 = 8641896
113 + 8641783 = 8641896
149 + 8641747 = 8641896
163 + 8641733 = 8641896

Showing the first eight; more decompositions exist.
