Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022256, here are decompositions:

5 + 1022251 = 1022256
7 + 1022249 = 1022256
13 + 1022243 = 1022256
19 + 1022237 = 1022256
47 + 1022209 = 1022256
73 + 1022183 = 1022256
89 + 1022167 = 1022256
127 + 1022129 = 1022256

Showing the first eight; more decompositions exist.
