Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016440, here are decompositions:

17 + 1016423 = 1016440
41 + 1016399 = 1016440
83 + 1016357 = 1016440
101 + 1016339 = 1016440
137 + 1016303 = 1016440
239 + 1016201 = 1016440
281 + 1016159 = 1016440
317 + 1016123 = 1016440

Showing the first eight; more decompositions exist.
