Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505186, here are decompositions:

5 + 505181 = 505186
29 + 505157 = 505186
47 + 505139 = 505186
89 + 505097 = 505186
113 + 505073 = 505186
137 + 505049 = 505186
197 + 504989 = 505186
233 + 504953 = 505186

Showing the first eight; more decompositions exist.
