Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026646, here are decompositions:

53 + 1026593 = 1026646
59 + 1026587 = 1026646
83 + 1026563 = 1026646
167 + 1026479 = 1026646
197 + 1026449 = 1026646
233 + 1026413 = 1026646
239 + 1026407 = 1026646
263 + 1026383 = 1026646

Showing the first eight; more decompositions exist.
