Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511232, here are decompositions:

19 + 511213 = 511232
31 + 511201 = 511232
61 + 511171 = 511232
79 + 511153 = 511232
109 + 511123 = 511232
193 + 511039 = 511232
199 + 511033 = 511232
313 + 510919 = 511232

Showing the first eight; more decompositions exist.
