Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026688, here are decompositions:

11 + 1026677 = 1026688
101 + 1026587 = 1026688
107 + 1026581 = 1026688
167 + 1026521 = 1026688
239 + 1026449 = 1026688
281 + 1026407 = 1026688
317 + 1026371 = 1026688
389 + 1026299 = 1026688

Showing the first eight; more decompositions exist.
