Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021160, here are decompositions:

3 + 1021157 = 1021160
31 + 1021129 = 1021160
37 + 1021123 = 1021160
67 + 1021093 = 1021160
73 + 1021087 = 1021160
79 + 1021081 = 1021160
163 + 1020997 = 1021160
181 + 1020979 = 1021160

Showing the first eight; more decompositions exist.
