Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521214, here are decompositions:

13 + 521201 = 521214
37 + 521177 = 521214
41 + 521173 = 521214
47 + 521167 = 521214
53 + 521161 = 521214
61 + 521153 = 521214
107 + 521107 = 521214
151 + 521063 = 521214

Showing the first eight; more decompositions exist.
