Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648970, here are decompositions:

17 + 8648953 = 8648970
41 + 8648929 = 8648970
47 + 8648923 = 8648970
89 + 8648881 = 8648970
103 + 8648867 = 8648970
107 + 8648863 = 8648970
131 + 8648839 = 8648970
137 + 8648833 = 8648970

Showing the first eight; more decompositions exist.
