Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505164, here are decompositions:

5 + 505159 = 505164
7 + 505157 = 505164
41 + 505123 = 505164
47 + 505117 = 505164
53 + 505111 = 505164
67 + 505097 = 505164
73 + 505091 = 505164
97 + 505067 = 505164

Showing the first eight; more decompositions exist.
