Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511932, here are decompositions:

23 + 511909 = 511932
41 + 511891 = 511932
59 + 511873 = 511932
73 + 511859 = 511932
89 + 511843 = 511932
101 + 511831 = 511932
131 + 511801 = 511932
139 + 511793 = 511932

Showing the first eight; more decompositions exist.
