Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051258, here are decompositions:

11 + 1051247 = 1051258
101 + 1051157 = 1051258
107 + 1051151 = 1051258
179 + 1051079 = 1051258
239 + 1051019 = 1051258
251 + 1051007 = 1051258
281 + 1050977 = 1051258
359 + 1050899 = 1051258

Showing the first eight; more decompositions exist.
