Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505072, here are decompositions:

5 + 505067 = 505072
11 + 505061 = 505072
23 + 505049 = 505072
41 + 505031 = 505072
83 + 504989 = 505072
89 + 504983 = 505072
179 + 504893 = 505072
251 + 504821 = 505072

Showing the first eight; more decompositions exist.
