Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511774, here are decompositions:

17 + 511757 = 511774
71 + 511703 = 511774
83 + 511691 = 511774
191 + 511583 = 511774
233 + 511541 = 511774
251 + 511523 = 511774
311 + 511463 = 511774
317 + 511457 = 511774

Showing the first eight; more decompositions exist.
