Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511756, here are decompositions:

53 + 511703 = 511756
173 + 511583 = 511756
197 + 511559 = 511756
233 + 511523 = 511756
269 + 511487 = 511756
293 + 511463 = 511756
317 + 511439 = 511756
347 + 511409 = 511756

Showing the first eight; more decompositions exist.
