Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987468, here are decompositions:

5 + 987463 = 987468
11 + 987457 = 987468
107 + 987361 = 987468
241 + 987227 = 987468
257 + 987211 = 987468
269 + 987199 = 987468
277 + 987191 = 987468
367 + 987101 = 987468

Showing the first eight; more decompositions exist.
