Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511372, here are decompositions:

11 + 511361 = 511372
83 + 511289 = 511372
149 + 511223 = 511372
179 + 511193 = 511372
263 + 511109 = 511372
311 + 511061 = 511372
353 + 511019 = 511372
359 + 511013 = 511372

Showing the first eight; more decompositions exist.
