Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002256, here are decompositions:

29 + 1002227 = 1002256
83 + 1002173 = 1002256
107 + 1002149 = 1002256
113 + 1002143 = 1002256
173 + 1002083 = 1002256
179 + 1002077 = 1002256
239 + 1002017 = 1002256
449 + 1001807 = 1002256

Showing the first eight; more decompositions exist.
