Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511814, here are decompositions:

3 + 511811 = 511814
13 + 511801 = 511814
103 + 511711 = 511814
181 + 511633 = 511814
211 + 511603 = 511814
223 + 511591 = 511814
241 + 511573 = 511814
307 + 511507 = 511814

Showing the first eight; more decompositions exist.
