Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512884, here are decompositions:

41 + 512843 = 512884
137 + 512747 = 512884
167 + 512717 = 512884
173 + 512711 = 512884
227 + 512657 = 512884
263 + 512621 = 512884
293 + 512591 = 512884
311 + 512573 = 512884

Showing the first eight; more decompositions exist.
