Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 965440, here are decompositions:

11 + 965429 = 965440
17 + 965423 = 965440
29 + 965411 = 965440
41 + 965399 = 965440
71 + 965369 = 965440
83 + 965357 = 965440
137 + 965303 = 965440
149 + 965291 = 965440

Showing the first eight; more decompositions exist.
