Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515598, here are decompositions:

11 + 515587 = 515598
19 + 515579 = 515598
59 + 515539 = 515598
79 + 515519 = 515598
197 + 515401 = 515598
227 + 515371 = 515598
229 + 515369 = 515598
241 + 515357 = 515598

Showing the first eight; more decompositions exist.
