Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511802, here are decompositions:

79 + 511723 = 511802
199 + 511603 = 511802
211 + 511591 = 511802
223 + 511579 = 511802
229 + 511573 = 511802
283 + 511519 = 511802
349 + 511453 = 511802
523 + 511279 = 511802

Showing the first eight; more decompositions exist.
