Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521332, here are decompositions:

3 + 521329 = 521332
23 + 521309 = 521332
89 + 521243 = 521332
101 + 521231 = 521332
131 + 521201 = 521332
179 + 521153 = 521332
269 + 521063 = 521332
281 + 521051 = 521332

Showing the first eight; more decompositions exist.
