Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511860, here are decompositions:

17 + 511843 = 511860
29 + 511831 = 511860
59 + 511801 = 511860
67 + 511793 = 511860
73 + 511787 = 511860
103 + 511757 = 511860
137 + 511723 = 511860
149 + 511711 = 511860

Showing the first eight; more decompositions exist.
