Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511382, here are decompositions:

31 + 511351 = 511382
103 + 511279 = 511382
139 + 511243 = 511382
181 + 511201 = 511382
211 + 511171 = 511382
229 + 511153 = 511382
271 + 511111 = 511382
349 + 511033 = 511382

Showing the first eight; more decompositions exist.
