Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521968, here are decompositions:

71 + 521897 = 521968
89 + 521879 = 521968
107 + 521861 = 521968
137 + 521831 = 521968
149 + 521819 = 521968
179 + 521789 = 521968
191 + 521777 = 521968
311 + 521657 = 521968

Showing the first eight; more decompositions exist.
