Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025520, here are decompositions:

7 + 1025513 = 1025520
11 + 1025509 = 1025520
17 + 1025503 = 1025520
37 + 1025483 = 1025520
43 + 1025477 = 1025520
61 + 1025459 = 1025520
101 + 1025419 = 1025520
103 + 1025417 = 1025520

Showing the first eight; more decompositions exist.
