Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617440, here are decompositions:

23 + 8617417 = 8617440
43 + 8617397 = 8617440
59 + 8617381 = 8617440
67 + 8617373 = 8617440
79 + 8617361 = 8617440
107 + 8617333 = 8617440
113 + 8617327 = 8617440
127 + 8617313 = 8617440

Showing the first eight; more decompositions exist.
