Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643460, here are decompositions:

3 + 8643457 = 8643460
17 + 8643443 = 8643460
101 + 8643359 = 8643460
173 + 8643287 = 8643460
179 + 8643281 = 8643460
251 + 8643209 = 8643460
263 + 8643197 = 8643460
311 + 8643149 = 8643460

Showing the first eight; more decompositions exist.
