Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505282, here are decompositions:

3 + 505279 = 505282
5 + 505277 = 505282
101 + 505181 = 505282
191 + 505091 = 505282
233 + 505049 = 505282
251 + 505031 = 505282
293 + 504989 = 505282
353 + 504929 = 505282

Showing the first eight; more decompositions exist.
