Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511444, here are decompositions:

5 + 511439 = 511444
53 + 511391 = 511444
83 + 511361 = 511444
107 + 511337 = 511444
233 + 511211 = 511444
251 + 511193 = 511444
281 + 511163 = 511444
293 + 511151 = 511444

Showing the first eight; more decompositions exist.
