Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525212, here are decompositions:

3 + 525209 = 525212
13 + 525199 = 525212
19 + 525193 = 525212
199 + 525013 = 525212
211 + 525001 = 525212
229 + 524983 = 525212
241 + 524971 = 525212
271 + 524941 = 525212

Showing the first eight; more decompositions exist.
