Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515998, here are decompositions:

5 + 515993 = 515998
29 + 515969 = 515998
47 + 515951 = 515998
137 + 515861 = 515998
227 + 515771 = 515998
257 + 515741 = 515998
311 + 515687 = 515998
317 + 515681 = 515998

Showing the first eight; more decompositions exist.
