Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607440, here are decompositions:

7 + 8607433 = 8607440
13 + 8607427 = 8607440
31 + 8607409 = 8607440
43 + 8607397 = 8607440
67 + 8607373 = 8607440
97 + 8607343 = 8607440
199 + 8607241 = 8607440
223 + 8607217 = 8607440

Showing the first eight; more decompositions exist.
