Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646460, here are decompositions:

3 + 8646457 = 8646460
59 + 8646401 = 8646460
71 + 8646389 = 8646460
83 + 8646377 = 8646460
131 + 8646329 = 8646460
167 + 8646293 = 8646460
191 + 8646269 = 8646460
227 + 8646233 = 8646460

Showing the first eight; more decompositions exist.
