Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511400, here are decompositions:

13 + 511387 = 511400
67 + 511333 = 511400
73 + 511327 = 511400
103 + 511297 = 511400
139 + 511261 = 511400
157 + 511243 = 511400
163 + 511237 = 511400
199 + 511201 = 511400

Showing the first eight; more decompositions exist.
