Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521342, here are decompositions:

13 + 521329 = 521342
43 + 521299 = 521342
61 + 521281 = 521342
163 + 521179 = 521342
181 + 521161 = 521342
223 + 521119 = 521342
373 + 520969 = 521342
379 + 520963 = 521342

Showing the first eight; more decompositions exist.
