Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606220, here are decompositions:

19 + 8606201 = 8606220
23 + 8606197 = 8606220
41 + 8606179 = 8606220
47 + 8606173 = 8606220
83 + 8606137 = 8606220
127 + 8606093 = 8606220
167 + 8606053 = 8606220
173 + 8606047 = 8606220

Showing the first eight; more decompositions exist.
