Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051156, here are decompositions:

3 + 1051153 = 1051156
5 + 1051151 = 1051156
17 + 1051139 = 1051156
137 + 1051019 = 1051156
149 + 1051007 = 1051156
179 + 1050977 = 1051156
257 + 1050899 = 1051156
269 + 1050887 = 1051156

Showing the first eight; more decompositions exist.
