Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016256, here are decompositions:

19 + 1016237 = 1016256
29 + 1016227 = 1016256
53 + 1016203 = 1016256
83 + 1016173 = 1016256
97 + 1016159 = 1016256
103 + 1016153 = 1016256
113 + 1016143 = 1016256
167 + 1016089 = 1016256

Showing the first eight; more decompositions exist.
