Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627418, here are decompositions:

47 + 8627371 = 8627418
61 + 8627357 = 8627418
67 + 8627351 = 8627418
89 + 8627329 = 8627418
97 + 8627321 = 8627418
167 + 8627251 = 8627418
227 + 8627191 = 8627418
251 + 8627167 = 8627418

Showing the first eight; more decompositions exist.
