Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511968, here are decompositions:

5 + 511963 = 511968
7 + 511961 = 511968
29 + 511939 = 511968
59 + 511909 = 511968
71 + 511897 = 511968
101 + 511867 = 511968
109 + 511859 = 511968
137 + 511831 = 511968

Showing the first eight; more decompositions exist.
