Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516556, here are decompositions:

17 + 516539 = 516556
107 + 516449 = 516556
149 + 516407 = 516556
179 + 516377 = 516556
197 + 516359 = 516556
233 + 516323 = 516556
263 + 516293 = 516556
347 + 516209 = 516556

Showing the first eight; more decompositions exist.
