Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025558, here are decompositions:

7 + 1025551 = 1025558
139 + 1025419 = 1025558
151 + 1025407 = 1025558
211 + 1025347 = 1025558
277 + 1025281 = 1025558
349 + 1025209 = 1025558
397 + 1025161 = 1025558
409 + 1025149 = 1025558

Showing the first eight; more decompositions exist.
