Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049878, here are decompositions:

17 + 1049861 = 1049878
29 + 1049849 = 1049878
41 + 1049837 = 1049878
131 + 1049747 = 1049878
191 + 1049687 = 1049878
197 + 1049681 = 1049878
239 + 1049639 = 1049878
359 + 1049519 = 1049878

Showing the first eight; more decompositions exist.
