Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518204, here are decompositions:

13 + 518191 = 518204
67 + 518137 = 518204
73 + 518131 = 518204
103 + 518101 = 518204
157 + 518047 = 518204
223 + 517981 = 518204
277 + 517927 = 518204
331 + 517873 = 518204

Showing the first eight; more decompositions exist.
