Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511892, here are decompositions:

19 + 511873 = 511892
61 + 511831 = 511892
181 + 511711 = 511892
223 + 511669 = 511892
313 + 511579 = 511892
373 + 511519 = 511892
439 + 511453 = 511892
541 + 511351 = 511892

Showing the first eight; more decompositions exist.
