Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516404, here are decompositions:

13 + 516391 = 516404
43 + 516361 = 516404
127 + 516277 = 516404
151 + 516253 = 516404
157 + 516247 = 516404
181 + 516223 = 516404
211 + 516193 = 516404
241 + 516163 = 516404

Showing the first eight; more decompositions exist.
