Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022160, here are decompositions:

19 + 1022141 = 1022160
23 + 1022137 = 1022160
31 + 1022129 = 1022160
37 + 1022123 = 1022160
47 + 1022113 = 1022160
89 + 1022071 = 1022160
101 + 1022059 = 1022160
107 + 1022053 = 1022160

Showing the first eight; more decompositions exist.
