Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027440, here are decompositions:

13 + 1027427 = 1027440
19 + 1027421 = 1027440
23 + 1027417 = 1027440
31 + 1027409 = 1027440
83 + 1027357 = 1027440
109 + 1027331 = 1027440
151 + 1027289 = 1027440
163 + 1027277 = 1027440

Showing the first eight; more decompositions exist.
