Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525478, here are decompositions:

11 + 525467 = 525478
17 + 525461 = 525478
47 + 525431 = 525478
101 + 525377 = 525478
179 + 525299 = 525478
257 + 525221 = 525478
269 + 525209 = 525478
311 + 525167 = 525478

Showing the first eight; more decompositions exist.
