Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511406, here are decompositions:

19 + 511387 = 511406
73 + 511333 = 511406
79 + 511327 = 511406
109 + 511297 = 511406
127 + 511279 = 511406
163 + 511243 = 511406
193 + 511213 = 511406
229 + 511177 = 511406

Showing the first eight; more decompositions exist.
