Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006256, here are decompositions:

3 + 1006253 = 1006256
7 + 1006249 = 1006256
19 + 1006237 = 1006256
37 + 1006219 = 1006256
67 + 1006189 = 1006256
79 + 1006177 = 1006256
103 + 1006153 = 1006256
109 + 1006147 = 1006256

Showing the first eight; more decompositions exist.
