Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522400, here are decompositions:

17 + 522383 = 522400
29 + 522371 = 522400
83 + 522317 = 522400
149 + 522251 = 522400
167 + 522233 = 522400
173 + 522227 = 522400
233 + 522167 = 522400
239 + 522161 = 522400

Showing the first eight; more decompositions exist.
