Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511874, here are decompositions:

7 + 511867 = 511874
31 + 511843 = 511874
43 + 511831 = 511874
73 + 511801 = 511874
151 + 511723 = 511874
163 + 511711 = 511874
241 + 511633 = 511874
271 + 511603 = 511874

Showing the first eight; more decompositions exist.
