Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511890, here are decompositions:

17 + 511873 = 511890
23 + 511867 = 511890
31 + 511859 = 511890
47 + 511843 = 511890
59 + 511831 = 511890
79 + 511811 = 511890
89 + 511801 = 511890
97 + 511793 = 511890

Showing the first eight; more decompositions exist.
