Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522646, here are decompositions:

23 + 522623 = 522646
149 + 522497 = 522646
167 + 522479 = 522646
197 + 522449 = 522646
233 + 522413 = 522646
263 + 522383 = 522646
419 + 522227 = 522646
479 + 522167 = 522646

Showing the first eight; more decompositions exist.
