Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522220, here are decompositions:

29 + 522191 = 522220
53 + 522167 = 522220
59 + 522161 = 522220
107 + 522113 = 522220
137 + 522083 = 522220
173 + 522047 = 522220
227 + 521993 = 522220
239 + 521981 = 522220

Showing the first eight; more decompositions exist.
