Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505658, here are decompositions:

19 + 505639 = 505658
157 + 505501 = 505658
199 + 505459 = 505658
211 + 505447 = 505658
229 + 505429 = 505658
331 + 505327 = 505658
337 + 505321 = 505658
379 + 505279 = 505658

Showing the first eight; more decompositions exist.
