Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511792, here are decompositions:

5 + 511787 = 511792
89 + 511703 = 511792
101 + 511691 = 511792
233 + 511559 = 511792
251 + 511541 = 511792
269 + 511523 = 511792
353 + 511439 = 511792
383 + 511409 = 511792

Showing the first eight; more decompositions exist.
