Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511466, here are decompositions:

3 + 511463 = 511466
13 + 511453 = 511466
19 + 511447 = 511466
79 + 511387 = 511466
139 + 511327 = 511466
223 + 511243 = 511466
229 + 511237 = 511466
313 + 511153 = 511466

Showing the first eight; more decompositions exist.
