Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515698, here are decompositions:

5 + 515693 = 515698
11 + 515687 = 515698
17 + 515681 = 515698
47 + 515651 = 515698
59 + 515639 = 515698
101 + 515597 = 515698
179 + 515519 = 515698
191 + 515507 = 515698

Showing the first eight; more decompositions exist.
