Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521190, here are decompositions:

11 + 521179 = 521190
13 + 521177 = 521190
17 + 521173 = 521190
23 + 521167 = 521190
29 + 521161 = 521190
37 + 521153 = 521190
53 + 521137 = 521190
71 + 521119 = 521190

Showing the first eight; more decompositions exist.
