Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627404, here are decompositions:

41 + 8627363 = 8627404
47 + 8627357 = 8627404
53 + 8627351 = 8627404
83 + 8627321 = 8627404
251 + 8627153 = 8627404
257 + 8627147 = 8627404
263 + 8627141 = 8627404
293 + 8627111 = 8627404

Showing the first eight; more decompositions exist.
