Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511280, here are decompositions:

19 + 511261 = 511280
37 + 511243 = 511280
43 + 511237 = 511280
67 + 511213 = 511280
79 + 511201 = 511280
103 + 511177 = 511280
109 + 511171 = 511280
127 + 511153 = 511280

Showing the first eight; more decompositions exist.
