Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511458, here are decompositions:

5 + 511453 = 511458
11 + 511447 = 511458
19 + 511439 = 511458
41 + 511417 = 511458
67 + 511391 = 511458
71 + 511387 = 511458
97 + 511361 = 511458
107 + 511351 = 511458

Showing the first eight; more decompositions exist.
