Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505628, here are decompositions:

127 + 505501 = 505628
181 + 505447 = 505628
199 + 505429 = 505628
229 + 505399 = 505628
271 + 505357 = 505628
307 + 505321 = 505628
349 + 505279 = 505628
397 + 505231 = 505628

Showing the first eight; more decompositions exist.
