Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641970, here are decompositions:

13 + 8641957 = 8641970
61 + 8641909 = 8641970
79 + 8641891 = 8641970
97 + 8641873 = 8641970
151 + 8641819 = 8641970
163 + 8641807 = 8641970
223 + 8641747 = 8641970
229 + 8641741 = 8641970

Showing the first eight; more decompositions exist.
