Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627440, here are decompositions:

11 + 8627429 = 8627440
23 + 8627417 = 8627440
83 + 8627357 = 8627440
89 + 8627351 = 8627440
197 + 8627243 = 8627440
293 + 8627147 = 8627440
359 + 8627081 = 8627440
383 + 8627057 = 8627440

Showing the first eight; more decompositions exist.
