Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643102, here are decompositions:

11 + 8643091 = 8643102
19 + 8643083 = 8643102
43 + 8643059 = 8643102
79 + 8643023 = 8643102
89 + 8643013 = 8643102
113 + 8642989 = 8643102
151 + 8642951 = 8643102
163 + 8642939 = 8643102

Showing the first eight; more decompositions exist.
