Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521432, here are decompositions:

3 + 521429 = 521432
31 + 521401 = 521432
73 + 521359 = 521432
103 + 521329 = 521432
151 + 521281 = 521432
181 + 521251 = 521432
271 + 521161 = 521432
313 + 521119 = 521432

Showing the first eight; more decompositions exist.
