Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521510, here are decompositions:

7 + 521503 = 521510
13 + 521497 = 521510
19 + 521491 = 521510
109 + 521401 = 521510
151 + 521359 = 521510
181 + 521329 = 521510
193 + 521317 = 521510
211 + 521299 = 521510

Showing the first eight; more decompositions exist.
