Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511284, here are decompositions:

5 + 511279 = 511284
23 + 511261 = 511284
41 + 511243 = 511284
47 + 511237 = 511284
61 + 511223 = 511284
71 + 511213 = 511284
73 + 511211 = 511284
83 + 511201 = 511284

Showing the first eight; more decompositions exist.
