Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001256, here are decompositions:

19 + 1001237 = 1001256
37 + 1001219 = 1001256
59 + 1001197 = 1001256
79 + 1001177 = 1001256
83 + 1001173 = 1001256
97 + 1001159 = 1001256
103 + 1001153 = 1001256
149 + 1001107 = 1001256

Showing the first eight; more decompositions exist.
