Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511862, here are decompositions:

3 + 511859 = 511862
19 + 511843 = 511862
31 + 511831 = 511862
61 + 511801 = 511862
139 + 511723 = 511862
151 + 511711 = 511862
193 + 511669 = 511862
229 + 511633 = 511862

Showing the first eight; more decompositions exist.
