Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525240, here are decompositions:

19 + 525221 = 525240
31 + 525209 = 525240
41 + 525199 = 525240
47 + 525193 = 525240
73 + 525167 = 525240
83 + 525157 = 525240
97 + 525143 = 525240
103 + 525137 = 525240

Showing the first eight; more decompositions exist.
