Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516208, here are decompositions:

29 + 516179 = 516208
47 + 516161 = 516208
131 + 516077 = 516208
191 + 516017 = 516208
239 + 515969 = 516208
257 + 515951 = 516208
347 + 515861 = 516208
431 + 515777 = 516208

Showing the first eight; more decompositions exist.
