Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522250, here are decompositions:

11 + 522239 = 522250
17 + 522233 = 522250
23 + 522227 = 522250
59 + 522191 = 522250
83 + 522167 = 522250
89 + 522161 = 522250
137 + 522113 = 522250
167 + 522083 = 522250

Showing the first eight; more decompositions exist.
