Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525306, here are decompositions:

7 + 525299 = 525306
53 + 525253 = 525306
59 + 525247 = 525306
97 + 525209 = 525306
107 + 525199 = 525306
113 + 525193 = 525306
139 + 525167 = 525306
149 + 525157 = 525306

Showing the first eight; more decompositions exist.
