Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512918, here are decompositions:

19 + 512899 = 512918
97 + 512821 = 512918
139 + 512779 = 512918
151 + 512767 = 512918
157 + 512761 = 512918
277 + 512641 = 512918
337 + 512581 = 512918
349 + 512569 = 512918

Showing the first eight; more decompositions exist.
