Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049820, here are decompositions:

11 + 1049809 = 1049820
29 + 1049791 = 1049820
47 + 1049773 = 1049820
73 + 1049747 = 1049820
103 + 1049717 = 1049820
113 + 1049707 = 1049820
137 + 1049683 = 1049820
139 + 1049681 = 1049820

Showing the first eight; more decompositions exist.
