Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511306, here are decompositions:

17 + 511289 = 511306
83 + 511223 = 511306
113 + 511193 = 511306
137 + 511169 = 511306
197 + 511109 = 511306
293 + 511013 = 511306
317 + 510989 = 511306
479 + 510827 = 511306

Showing the first eight; more decompositions exist.
