Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505160, here are decompositions:

3 + 505157 = 505160
31 + 505129 = 505160
37 + 505123 = 505160
43 + 505117 = 505160
109 + 505051 = 505160
127 + 505033 = 505160
193 + 504967 = 505160
223 + 504937 = 505160

Showing the first eight; more decompositions exist.
