Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522800, here are decompositions:

13 + 522787 = 522800
37 + 522763 = 522800
43 + 522757 = 522800
97 + 522703 = 522800
127 + 522673 = 522800
139 + 522661 = 522800
163 + 522637 = 522800
199 + 522601 = 522800

Showing the first eight; more decompositions exist.
