Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049920, here are decompositions:

23 + 1049897 = 1049920
29 + 1049891 = 1049920
59 + 1049861 = 1049920
71 + 1049849 = 1049920
83 + 1049837 = 1049920
173 + 1049747 = 1049920
233 + 1049687 = 1049920
239 + 1049681 = 1049920

Showing the first eight; more decompositions exist.
