Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522280, here are decompositions:

29 + 522251 = 522280
41 + 522239 = 522280
47 + 522233 = 522280
53 + 522227 = 522280
89 + 522191 = 522280
113 + 522167 = 522280
167 + 522113 = 522280
197 + 522083 = 522280

Showing the first eight; more decompositions exist.
