Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051806, here are decompositions:

17 + 1051789 = 1051806
43 + 1051763 = 1051806
47 + 1051759 = 1051806
59 + 1051747 = 1051806
89 + 1051717 = 1051806
97 + 1051709 = 1051806
109 + 1051697 = 1051806
157 + 1051649 = 1051806

Showing the first eight; more decompositions exist.
