Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511876, here are decompositions:

3 + 511873 = 511876
17 + 511859 = 511876
83 + 511793 = 511876
89 + 511787 = 511876
173 + 511703 = 511876
293 + 511583 = 511876
317 + 511559 = 511876
353 + 511523 = 511876

Showing the first eight; more decompositions exist.
