Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039440, here are decompositions:

11 + 1039429 = 1039440
13 + 1039427 = 1039440
19 + 1039421 = 1039440
53 + 1039387 = 1039440
89 + 1039351 = 1039440
97 + 1039343 = 1039440
113 + 1039327 = 1039440
151 + 1039289 = 1039440

Showing the first eight; more decompositions exist.
