Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1037820, here are decompositions:

19 + 1037801 = 1037820
29 + 1037791 = 1037820
53 + 1037767 = 1037820
61 + 1037759 = 1037820
67 + 1037753 = 1037820
73 + 1037747 = 1037820
79 + 1037741 = 1037820
137 + 1037683 = 1037820

Showing the first eight; more decompositions exist.
