Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511402, here are decompositions:

11 + 511391 = 511402
41 + 511361 = 511402
113 + 511289 = 511402
179 + 511223 = 511402
191 + 511211 = 511402
233 + 511169 = 511402
239 + 511163 = 511402
251 + 511151 = 511402

Showing the first eight; more decompositions exist.
