Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025398, here are decompositions:

5 + 1025393 = 1025398
47 + 1025351 = 1025398
71 + 1025327 = 1025398
131 + 1025267 = 1025398
137 + 1025261 = 1025398
167 + 1025231 = 1025398
251 + 1025147 = 1025398
317 + 1025081 = 1025398

Showing the first eight; more decompositions exist.
