Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553806, here are decompositions:

17 + 553789 = 553806
37 + 553769 = 553806
47 + 553759 = 553806
59 + 553747 = 553806
73 + 553733 = 553806
79 + 553727 = 553806
103 + 553703 = 553806
107 + 553699 = 553806

Showing the first eight; more decompositions exist.
