Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521352, here are decompositions:

23 + 521329 = 521352
43 + 521309 = 521352
53 + 521299 = 521352
71 + 521281 = 521352
101 + 521251 = 521352
109 + 521243 = 521352
151 + 521201 = 521352
173 + 521179 = 521352

Showing the first eight; more decompositions exist.
