Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605408, here are decompositions:

5 + 8605403 = 8605408
29 + 8605379 = 8605408
47 + 8605361 = 8605408
89 + 8605319 = 8605408
101 + 8605307 = 8605408
167 + 8605241 = 8605408
179 + 8605229 = 8605408
191 + 8605217 = 8605408

Showing the first eight; more decompositions exist.
