Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511848, here are decompositions:

5 + 511843 = 511848
17 + 511831 = 511848
37 + 511811 = 511848
47 + 511801 = 511848
61 + 511787 = 511848
137 + 511711 = 511848
157 + 511691 = 511848
179 + 511669 = 511848

Showing the first eight; more decompositions exist.
