Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536820, here are decompositions:

17 + 536803 = 536820
19 + 536801 = 536820
29 + 536791 = 536820
41 + 536779 = 536820
43 + 536777 = 536820
47 + 536773 = 536820
71 + 536749 = 536820
101 + 536719 = 536820

Showing the first eight; more decompositions exist.
