Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051260, here are decompositions:

13 + 1051247 = 1051260
79 + 1051181 = 1051260
83 + 1051177 = 1051260
103 + 1051157 = 1051260
107 + 1051153 = 1051260
109 + 1051151 = 1051260
113 + 1051147 = 1051260
179 + 1051081 = 1051260

Showing the first eight; more decompositions exist.
