Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522810, here are decompositions:

23 + 522787 = 522810
47 + 522763 = 522810
53 + 522757 = 522810
61 + 522749 = 522810
73 + 522737 = 522810
103 + 522707 = 522810
107 + 522703 = 522810
131 + 522679 = 522810

Showing the first eight; more decompositions exist.
