Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505210, here are decompositions:

23 + 505187 = 505210
29 + 505181 = 505210
53 + 505157 = 505210
71 + 505139 = 505210
113 + 505097 = 505210
137 + 505073 = 505210
149 + 505061 = 505210
179 + 505031 = 505210

Showing the first eight; more decompositions exist.
