Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511942, here are decompositions:

3 + 511939 = 511942
83 + 511859 = 511942
131 + 511811 = 511942
149 + 511793 = 511942
239 + 511703 = 511942
251 + 511691 = 511942
311 + 511631 = 511942
359 + 511583 = 511942

Showing the first eight; more decompositions exist.
