Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529858, here are decompositions:

11 + 529847 = 529858
29 + 529829 = 529858
47 + 529811 = 529858
107 + 529751 = 529858
149 + 529709 = 529858
167 + 529691 = 529858
239 + 529619 = 529858
281 + 529577 = 529858

Showing the first eight; more decompositions exist.
