Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522478, here are decompositions:

29 + 522449 = 522478
107 + 522371 = 522478
197 + 522281 = 522478
227 + 522251 = 522478
239 + 522239 = 522478
251 + 522227 = 522478
311 + 522167 = 522478
317 + 522161 = 522478

Showing the first eight; more decompositions exist.
