Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608440, here are decompositions:

11 + 8608429 = 8608440
13 + 8608427 = 8608440
17 + 8608423 = 8608440
41 + 8608399 = 8608440
67 + 8608373 = 8608440
83 + 8608357 = 8608440
107 + 8608333 = 8608440
149 + 8608291 = 8608440

Showing the first eight; more decompositions exist.
