Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638606, here are decompositions:

23 + 8638583 = 8638606
89 + 8638517 = 8638606
149 + 8638457 = 8638606
227 + 8638379 = 8638606
233 + 8638373 = 8638606
257 + 8638349 = 8638606
269 + 8638337 = 8638606
359 + 8638247 = 8638606

Showing the first eight; more decompositions exist.
