Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025666, here are decompositions:

7 + 1025659 = 1025666
13 + 1025653 = 1025666
43 + 1025623 = 1025666
157 + 1025509 = 1025666
163 + 1025503 = 1025666
223 + 1025443 = 1025666
283 + 1025383 = 1025666
409 + 1025257 = 1025666

Showing the first eight; more decompositions exist.
