Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511348, here are decompositions:

11 + 511337 = 511348
59 + 511289 = 511348
137 + 511211 = 511348
179 + 511169 = 511348
197 + 511151 = 511348
239 + 511109 = 511348
347 + 511001 = 511348
359 + 510989 = 511348

Showing the first eight; more decompositions exist.
