Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031440, here are decompositions:

17 + 1031423 = 1031440
29 + 1031411 = 1031440
41 + 1031399 = 1031440
83 + 1031357 = 1031440
131 + 1031309 = 1031440
149 + 1031291 = 1031440
173 + 1031267 = 1031440
251 + 1031189 = 1031440

Showing the first eight; more decompositions exist.
