Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520164, here are decompositions:

13 + 520151 = 520164
41 + 520123 = 520164
53 + 520111 = 520164
61 + 520103 = 520164
97 + 520067 = 520164
101 + 520063 = 520164
167 + 519997 = 520164
193 + 519971 = 520164

Showing the first eight; more decompositions exist.
