Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505182, here are decompositions:

23 + 505159 = 505182
43 + 505139 = 505182
53 + 505129 = 505182
59 + 505123 = 505182
71 + 505111 = 505182
109 + 505073 = 505182
131 + 505051 = 505182
149 + 505033 = 505182

Showing the first eight; more decompositions exist.
