Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511846, here are decompositions:

3 + 511843 = 511846
53 + 511793 = 511846
59 + 511787 = 511846
89 + 511757 = 511846
263 + 511583 = 511846
359 + 511487 = 511846
383 + 511463 = 511846
389 + 511457 = 511846

Showing the first eight; more decompositions exist.
