Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609220, here are decompositions:

13 + 8609207 = 8609220
47 + 8609173 = 8609220
71 + 8609149 = 8609220
83 + 8609137 = 8609220
101 + 8609119 = 8609220
127 + 8609093 = 8609220
157 + 8609063 = 8609220
197 + 8609023 = 8609220

Showing the first eight; more decompositions exist.
