Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051288, here are decompositions:

5 + 1051283 = 1051288
11 + 1051277 = 1051288
41 + 1051247 = 1051288
107 + 1051181 = 1051288
131 + 1051157 = 1051288
137 + 1051151 = 1051288
149 + 1051139 = 1051288
269 + 1051019 = 1051288

Showing the first eight; more decompositions exist.
