Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042856, here are decompositions:

7 + 1042849 = 1042856
19 + 1042837 = 1042856
37 + 1042819 = 1042856
97 + 1042759 = 1042856
163 + 1042693 = 1042856
223 + 1042633 = 1042856
337 + 1042519 = 1042856
457 + 1042399 = 1042856

Showing the first eight; more decompositions exist.
