Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512916, here are decompositions:

13 + 512903 = 512916
17 + 512899 = 512916
67 + 512849 = 512916
73 + 512843 = 512916
97 + 512819 = 512916
113 + 512803 = 512916
137 + 512779 = 512916
149 + 512767 = 512916

Showing the first eight; more decompositions exist.
