Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512780, here are decompositions:

13 + 512767 = 512780
19 + 512761 = 512780
67 + 512713 = 512780
97 + 512683 = 512780
109 + 512671 = 512780
139 + 512641 = 512780
199 + 512581 = 512780
211 + 512569 = 512780

Showing the first eight; more decompositions exist.
