Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608220, here are decompositions:

3 + 8608217 = 8608220
37 + 8608183 = 8608220
73 + 8608147 = 8608220
139 + 8608081 = 8608220
193 + 8608027 = 8608220
211 + 8608009 = 8608220
223 + 8607997 = 8608220
277 + 8607943 = 8608220

Showing the first eight; more decompositions exist.
