Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511854, here are decompositions:

11 + 511843 = 511854
23 + 511831 = 511854
43 + 511811 = 511854
53 + 511801 = 511854
61 + 511793 = 511854
67 + 511787 = 511854
97 + 511757 = 511854
131 + 511723 = 511854

Showing the first eight; more decompositions exist.
