Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642466, here are decompositions:

13 + 8642453 = 8642466
17 + 8642449 = 8642466
37 + 8642429 = 8642466
83 + 8642383 = 8642466
137 + 8642329 = 8642466
163 + 8642303 = 8642466
229 + 8642237 = 8642466
269 + 8642197 = 8642466

Showing the first eight; more decompositions exist.
