Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520160, here are decompositions:

31 + 520129 = 520160
37 + 520123 = 520160
97 + 520063 = 520160
139 + 520021 = 520160
163 + 519997 = 520160
229 + 519931 = 520160
241 + 519919 = 520160
271 + 519889 = 520160

Showing the first eight; more decompositions exist.
