Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511018, here are decompositions:

5 + 511013 = 511018
17 + 511001 = 511018
29 + 510989 = 511018
191 + 510827 = 511018
251 + 510767 = 511018
311 + 510707 = 511018
401 + 510617 = 511018
449 + 510569 = 511018

Showing the first eight; more decompositions exist.
