Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512838, here are decompositions:

17 + 512821 = 512838
19 + 512819 = 512838
41 + 512797 = 512838
59 + 512779 = 512838
71 + 512767 = 512838
97 + 512741 = 512838
127 + 512711 = 512838
167 + 512671 = 512838

Showing the first eight; more decompositions exist.
