Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505170, here are decompositions:

11 + 505159 = 505170
13 + 505157 = 505170
31 + 505139 = 505170
41 + 505129 = 505170
47 + 505123 = 505170
53 + 505117 = 505170
59 + 505111 = 505170
73 + 505097 = 505170

Showing the first eight; more decompositions exist.
