Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511660, here are decompositions:

29 + 511631 = 511660
101 + 511559 = 511660
137 + 511523 = 511660
173 + 511487 = 511660
197 + 511463 = 511660
251 + 511409 = 511660
269 + 511391 = 511660
449 + 511211 = 511660

Showing the first eight; more decompositions exist.
