Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525448, here are decompositions:

17 + 525431 = 525448
71 + 525377 = 525448
89 + 525359 = 525448
149 + 525299 = 525448
191 + 525257 = 525448
227 + 525221 = 525448
239 + 525209 = 525448
257 + 525191 = 525448

Showing the first eight; more decompositions exist.
