Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518066, here are decompositions:

7 + 518059 = 518066
19 + 518047 = 518066
67 + 517999 = 518066
139 + 517927 = 518066
193 + 517873 = 518066
337 + 517729 = 518066
349 + 517717 = 518066
457 + 517609 = 518066

Showing the first eight; more decompositions exist.
