Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511318, here are decompositions:

29 + 511289 = 511318
107 + 511211 = 511318
149 + 511169 = 511318
167 + 511151 = 511318
257 + 511061 = 511318
317 + 511001 = 511318
491 + 510827 = 511318
641 + 510677 = 511318

Showing the first eight; more decompositions exist.
