Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047856, here are decompositions:

23 + 1047833 = 1047856
83 + 1047773 = 1047856
167 + 1047689 = 1047856
269 + 1047587 = 1047856
317 + 1047539 = 1047856
389 + 1047467 = 1047856
617 + 1047239 = 1047856
659 + 1047197 = 1047856

Showing the first eight; more decompositions exist.
