Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512788, here are decompositions:

41 + 512747 = 512788
47 + 512741 = 512788
71 + 512717 = 512788
131 + 512657 = 512788
167 + 512621 = 512788
179 + 512609 = 512788
191 + 512597 = 512788
197 + 512591 = 512788

Showing the first eight; more decompositions exist.
