Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511834, here are decompositions:

3 + 511831 = 511834
23 + 511811 = 511834
41 + 511793 = 511834
47 + 511787 = 511834
131 + 511703 = 511834
251 + 511583 = 511834
293 + 511541 = 511834
311 + 511523 = 511834

Showing the first eight; more decompositions exist.
