Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516240, here are decompositions:

7 + 516233 = 516240
13 + 516227 = 516240
17 + 516223 = 516240
31 + 516209 = 516240
41 + 516199 = 516240
47 + 516193 = 516240
61 + 516179 = 516240
71 + 516169 = 516240

Showing the first eight; more decompositions exist.
