Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511812, here are decompositions:

11 + 511801 = 511812
19 + 511793 = 511812
89 + 511723 = 511812
101 + 511711 = 511812
109 + 511703 = 511812
179 + 511633 = 511812
181 + 511631 = 511812
229 + 511583 = 511812

Showing the first eight; more decompositions exist.
