Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025568, here are decompositions:

7 + 1025561 = 1025568
17 + 1025551 = 1025568
31 + 1025537 = 1025568
59 + 1025509 = 1025568
109 + 1025459 = 1025568
149 + 1025419 = 1025568
151 + 1025417 = 1025568
241 + 1025327 = 1025568

Showing the first eight; more decompositions exist.
