Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505136, here are decompositions:

7 + 505129 = 505136
13 + 505123 = 505136
19 + 505117 = 505136
103 + 505033 = 505136
109 + 505027 = 505136
193 + 504943 = 505136
199 + 504937 = 505136
283 + 504853 = 505136

Showing the first eight; more decompositions exist.
