Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505258, here are decompositions:

71 + 505187 = 505258
101 + 505157 = 505258
167 + 505091 = 505258
191 + 505067 = 505258
197 + 505061 = 505258
227 + 505031 = 505258
269 + 504989 = 505258
311 + 504947 = 505258

Showing the first eight; more decompositions exist.
