Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516080, here are decompositions:

3 + 516077 = 516080
31 + 516049 = 516080
139 + 515941 = 516080
151 + 515929 = 516080
157 + 515923 = 516080
163 + 515917 = 516080
193 + 515887 = 516080
223 + 515857 = 516080

Showing the first eight; more decompositions exist.
