Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025570, here are decompositions:

19 + 1025551 = 1025570
61 + 1025509 = 1025570
67 + 1025503 = 1025570
127 + 1025443 = 1025570
151 + 1025419 = 1025570
157 + 1025413 = 1025570
163 + 1025407 = 1025570
223 + 1025347 = 1025570

Showing the first eight; more decompositions exist.
