Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521302, here are decompositions:

3 + 521299 = 521302
59 + 521243 = 521302
71 + 521231 = 521302
101 + 521201 = 521302
149 + 521153 = 521302
239 + 521063 = 521302
251 + 521051 = 521302
263 + 521039 = 521302

Showing the first eight; more decompositions exist.
