Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517438, here are decompositions:

71 + 517367 = 517438
101 + 517337 = 517438
149 + 517289 = 517438
197 + 517241 = 517438
227 + 517211 = 517438
269 + 517169 = 517438
347 + 517091 = 517438
359 + 517079 = 517438

Showing the first eight; more decompositions exist.
