Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627388, here are decompositions:

17 + 8627371 = 8627388
31 + 8627357 = 8627388
37 + 8627351 = 8627388
47 + 8627341 = 8627388
59 + 8627329 = 8627388
67 + 8627321 = 8627388
89 + 8627299 = 8627388
131 + 8627257 = 8627388

Showing the first eight; more decompositions exist.
