Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525628, here are decompositions:

29 + 525599 = 525628
137 + 525491 = 525628
167 + 525461 = 525628
197 + 525431 = 525628
251 + 525377 = 525628
269 + 525359 = 525628
419 + 525209 = 525628
461 + 525167 = 525628

Showing the first eight; more decompositions exist.
