Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021256, here are decompositions:

3 + 1021253 = 1021256
13 + 1021243 = 1021256
73 + 1021183 = 1021256
97 + 1021159 = 1021256
127 + 1021129 = 1021256
163 + 1021093 = 1021256
277 + 1020979 = 1021256
283 + 1020973 = 1021256

Showing the first eight; more decompositions exist.
