Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511732, here are decompositions:

29 + 511703 = 511732
41 + 511691 = 511732
101 + 511631 = 511732
149 + 511583 = 511732
173 + 511559 = 511732
191 + 511541 = 511732
269 + 511463 = 511732
293 + 511439 = 511732

Showing the first eight; more decompositions exist.
