Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511752, here are decompositions:

29 + 511723 = 511752
41 + 511711 = 511752
61 + 511691 = 511752
83 + 511669 = 511752
149 + 511603 = 511752
173 + 511579 = 511752
179 + 511573 = 511752
193 + 511559 = 511752

Showing the first eight; more decompositions exist.
