Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940864, here are decompositions:

11 + 940853 = 940864
47 + 940817 = 940864
83 + 940781 = 940864
131 + 940733 = 940864
137 + 940727 = 940864
173 + 940691 = 940864
257 + 940607 = 940864
311 + 940553 = 940864

Showing the first eight; more decompositions exist.
