Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515464, here are decompositions:

83 + 515381 = 515464
107 + 515357 = 515464
113 + 515351 = 515464
227 + 515237 = 515464
233 + 515231 = 515464
311 + 515153 = 515464
353 + 515111 = 515464
617 + 514847 = 515464

Showing the first eight; more decompositions exist.
