Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540512, here are decompositions:

3 + 540509 = 540512
43 + 540469 = 540512
79 + 540433 = 540512
139 + 540373 = 540512
163 + 540349 = 540512
211 + 540301 = 540512
229 + 540283 = 540512
241 + 540271 = 540512

Showing the first eight; more decompositions exist.
