Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511252, here are decompositions:

29 + 511223 = 511252
41 + 511211 = 511252
59 + 511193 = 511252
83 + 511169 = 511252
89 + 511163 = 511252
101 + 511151 = 511252
191 + 511061 = 511252
233 + 511019 = 511252

Showing the first eight; more decompositions exist.
