Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511424, here are decompositions:

7 + 511417 = 511424
37 + 511387 = 511424
73 + 511351 = 511424
97 + 511327 = 511424
127 + 511297 = 511424
163 + 511261 = 511424
181 + 511243 = 511424
211 + 511213 = 511424

Showing the first eight; more decompositions exist.
