Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521348, here are decompositions:

19 + 521329 = 521348
31 + 521317 = 521348
67 + 521281 = 521348
97 + 521251 = 521348
181 + 521167 = 521348
211 + 521137 = 521348
229 + 521119 = 521348
241 + 521107 = 521348

Showing the first eight; more decompositions exist.
