Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645466, here are decompositions:

17 + 8645449 = 8645466
23 + 8645443 = 8645466
59 + 8645407 = 8645466
107 + 8645359 = 8645466
113 + 8645353 = 8645466
139 + 8645327 = 8645466
173 + 8645293 = 8645466
197 + 8645269 = 8645466

Showing the first eight; more decompositions exist.
