Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515458, here are decompositions:

29 + 515429 = 515458
89 + 515369 = 515458
101 + 515357 = 515458
107 + 515351 = 515458
179 + 515279 = 515458
227 + 515231 = 515458
347 + 515111 = 515458
491 + 514967 = 515458

Showing the first eight; more decompositions exist.
