Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025422, here are decompositions:

3 + 1025419 = 1025422
5 + 1025417 = 1025422
29 + 1025393 = 1025422
71 + 1025351 = 1025422
89 + 1025333 = 1025422
149 + 1025273 = 1025422
191 + 1025231 = 1025422
269 + 1025153 = 1025422

Showing the first eight; more decompositions exist.
