Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614440, here are decompositions:

31 + 8614409 = 8614440
59 + 8614381 = 8614440
71 + 8614369 = 8614440
83 + 8614357 = 8614440
103 + 8614337 = 8614440
113 + 8614327 = 8614440
127 + 8614313 = 8614440
167 + 8614273 = 8614440

Showing the first eight; more decompositions exist.
