Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517930, here are decompositions:

3 + 517927 = 517930
11 + 517919 = 517930
29 + 517901 = 517930
53 + 517877 = 517930
107 + 517823 = 517930
113 + 517817 = 517930
191 + 517739 = 517930
197 + 517733 = 517930

Showing the first eight; more decompositions exist.
