Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605420, here are decompositions:

17 + 8605403 = 8605420
41 + 8605379 = 8605420
59 + 8605361 = 8605420
101 + 8605319 = 8605420
113 + 8605307 = 8605420
179 + 8605241 = 8605420
191 + 8605229 = 8605420
233 + 8605187 = 8605420

Showing the first eight; more decompositions exist.
