Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511974, here are decompositions:

11 + 511963 = 511974
13 + 511961 = 511974
41 + 511933 = 511974
83 + 511891 = 511974
101 + 511873 = 511974
107 + 511867 = 511974
131 + 511843 = 511974
163 + 511811 = 511974

Showing the first eight; more decompositions exist.
