Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604220, here are decompositions:

11 + 8604209 = 8604220
17 + 8604203 = 8604220
59 + 8604161 = 8604220
101 + 8604119 = 8604220
113 + 8604107 = 8604220
137 + 8604083 = 8604220
257 + 8603963 = 8604220
269 + 8603951 = 8604220

Showing the first eight; more decompositions exist.
