Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521212, here are decompositions:

11 + 521201 = 521212
59 + 521153 = 521212
149 + 521063 = 521212
173 + 521039 = 521212
191 + 521021 = 521212
269 + 520943 = 521212
359 + 520853 = 521212
449 + 520763 = 521212

Showing the first eight; more decompositions exist.
