Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511916, here are decompositions:

7 + 511909 = 511916
19 + 511897 = 511916
43 + 511873 = 511916
73 + 511843 = 511916
193 + 511723 = 511916
283 + 511633 = 511916
313 + 511603 = 511916
337 + 511579 = 511916

Showing the first eight; more decompositions exist.
