Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521164, here are decompositions:

3 + 521161 = 521164
11 + 521153 = 521164
101 + 521063 = 521164
113 + 521051 = 521164
197 + 520967 = 521164
251 + 520913 = 521164
311 + 520853 = 521164
401 + 520763 = 521164

Showing the first eight; more decompositions exist.
