Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022180, here are decompositions:

13 + 1022167 = 1022180
43 + 1022137 = 1022180
67 + 1022113 = 1022180
97 + 1022083 = 1022180
109 + 1022071 = 1022180
127 + 1022053 = 1022180
163 + 1022017 = 1022180
283 + 1021897 = 1022180

Showing the first eight; more decompositions exist.
