Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511902, here are decompositions:

5 + 511897 = 511902
11 + 511891 = 511902
29 + 511873 = 511902
43 + 511859 = 511902
59 + 511843 = 511902
71 + 511831 = 511902
101 + 511801 = 511902
109 + 511793 = 511902

Showing the first eight; more decompositions exist.
