Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649466, here are decompositions:

3 + 8649463 = 8649466
47 + 8649419 = 8649466
83 + 8649383 = 8649466
113 + 8649353 = 8649466
149 + 8649317 = 8649466
167 + 8649299 = 8649466
173 + 8649293 = 8649466
227 + 8649239 = 8649466

Showing the first eight; more decompositions exist.
