Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628460, here are decompositions:

11 + 8628449 = 8628460
17 + 8628443 = 8628460
53 + 8628407 = 8628460
83 + 8628377 = 8628460
101 + 8628359 = 8628460
107 + 8628353 = 8628460
167 + 8628293 = 8628460
227 + 8628233 = 8628460

Showing the first eight; more decompositions exist.
