Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529818, here are decompositions:

5 + 529813 = 529818
7 + 529811 = 529818
11 + 529807 = 529818
67 + 529751 = 529818
71 + 529747 = 529818
109 + 529709 = 529818
127 + 529691 = 529818
131 + 529687 = 529818

Showing the first eight; more decompositions exist.
