Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645430, here are decompositions:

23 + 8645407 = 8645430
71 + 8645359 = 8645430
89 + 8645341 = 8645430
103 + 8645327 = 8645430
137 + 8645293 = 8645430
149 + 8645281 = 8645430
163 + 8645267 = 8645430
173 + 8645257 = 8645430

Showing the first eight; more decompositions exist.
