Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042878, here are decompositions:

17 + 1042861 = 1042878
29 + 1042849 = 1042878
41 + 1042837 = 1042878
59 + 1042819 = 1042878
79 + 1042799 = 1042878
97 + 1042781 = 1042878
191 + 1042687 = 1042878
197 + 1042681 = 1042878

Showing the first eight; more decompositions exist.
