Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025566, here are decompositions:

5 + 1025561 = 1025566
23 + 1025543 = 1025566
29 + 1025537 = 1025566
53 + 1025513 = 1025566
83 + 1025483 = 1025566
89 + 1025477 = 1025566
107 + 1025459 = 1025566
149 + 1025417 = 1025566

Showing the first eight; more decompositions exist.
