Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605378, here are decompositions:

17 + 8605361 = 8605378
59 + 8605319 = 8605378
71 + 8605307 = 8605378
137 + 8605241 = 8605378
149 + 8605229 = 8605378
167 + 8605211 = 8605378
191 + 8605187 = 8605378
317 + 8605061 = 8605378

Showing the first eight; more decompositions exist.
