Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516280, here are decompositions:

3 + 516277 = 516280
29 + 516251 = 516280
47 + 516233 = 516280
53 + 516227 = 516280
71 + 516209 = 516280
101 + 516179 = 516280
227 + 516053 = 516280
257 + 516023 = 516280

Showing the first eight; more decompositions exist.
