Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025658, here are decompositions:

5 + 1025653 = 1025658
17 + 1025641 = 1025658
37 + 1025621 = 1025658
47 + 1025611 = 1025658
79 + 1025579 = 1025658
97 + 1025561 = 1025658
107 + 1025551 = 1025658
149 + 1025509 = 1025658

Showing the first eight; more decompositions exist.
