Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025918, here are decompositions:

7 + 1025911 = 1025918
31 + 1025887 = 1025918
79 + 1025839 = 1025918
151 + 1025767 = 1025918
211 + 1025707 = 1025918
277 + 1025641 = 1025918
307 + 1025611 = 1025918
367 + 1025551 = 1025918

Showing the first eight; more decompositions exist.
