Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505242, here are decompositions:

5 + 505237 = 505242
11 + 505231 = 505242
29 + 505213 = 505242
41 + 505201 = 505242
61 + 505181 = 505242
83 + 505159 = 505242
103 + 505139 = 505242
113 + 505129 = 505242

Showing the first eight; more decompositions exist.
