Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042886, here are decompositions:

37 + 1042849 = 1042886
67 + 1042819 = 1042886
127 + 1042759 = 1042886
193 + 1042693 = 1042886
199 + 1042687 = 1042886
277 + 1042609 = 1042886
367 + 1042519 = 1042886
487 + 1042399 = 1042886

Showing the first eight; more decompositions exist.
