Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518200, here are decompositions:

29 + 518171 = 518200
41 + 518159 = 518200
47 + 518153 = 518200
71 + 518129 = 518200
101 + 518099 = 518200
233 + 517967 = 518200
251 + 517949 = 518200
269 + 517931 = 518200

Showing the first eight; more decompositions exist.
