Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021168, here are decompositions:

11 + 1021157 = 1021168
41 + 1021127 = 1021168
101 + 1021067 = 1021168
149 + 1021019 = 1021168
167 + 1021001 = 1021168
179 + 1020989 = 1021168
191 + 1020977 = 1021168
347 + 1020821 = 1021168

Showing the first eight; more decompositions exist.
