Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536818, here are decompositions:

17 + 536801 = 536818
41 + 536777 = 536818
47 + 536771 = 536818
89 + 536729 = 536818
101 + 536717 = 536818
131 + 536687 = 536818
167 + 536651 = 536818
197 + 536621 = 536818

Showing the first eight; more decompositions exist.
