Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043820, here are decompositions:

47 + 1043773 = 1043820
53 + 1043767 = 1043820
59 + 1043761 = 1043820
61 + 1043759 = 1043820
67 + 1043753 = 1043820
73 + 1043747 = 1043820
97 + 1043723 = 1043820
137 + 1043683 = 1043820

Showing the first eight; more decompositions exist.
