Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511794, here are decompositions:

7 + 511787 = 511794
37 + 511757 = 511794
71 + 511723 = 511794
83 + 511711 = 511794
103 + 511691 = 511794
163 + 511631 = 511794
167 + 511627 = 511794
191 + 511603 = 511794

Showing the first eight; more decompositions exist.
