Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511908, here are decompositions:

11 + 511897 = 511908
17 + 511891 = 511908
41 + 511867 = 511908
97 + 511811 = 511908
107 + 511801 = 511908
151 + 511757 = 511908
197 + 511711 = 511908
239 + 511669 = 511908

Showing the first eight; more decompositions exist.
