Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511858, here are decompositions:

47 + 511811 = 511858
71 + 511787 = 511858
101 + 511757 = 511858
167 + 511691 = 511858
227 + 511631 = 511858
317 + 511541 = 511858
401 + 511457 = 511858
419 + 511439 = 511858

Showing the first eight; more decompositions exist.
