Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511454, here are decompositions:

7 + 511447 = 511454
37 + 511417 = 511454
67 + 511387 = 511454
103 + 511351 = 511454
127 + 511327 = 511454
157 + 511297 = 511454
193 + 511261 = 511454
211 + 511243 = 511454

Showing the first eight; more decompositions exist.
