Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022178, here are decompositions:

11 + 1022167 = 1022178
37 + 1022141 = 1022178
41 + 1022137 = 1022178
107 + 1022071 = 1022178
167 + 1022011 = 1022178
271 + 1021907 = 1022178
281 + 1021897 = 1022178
317 + 1021861 = 1022178

Showing the first eight; more decompositions exist.
