Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022090, here are decompositions:

7 + 1022083 = 1022090
19 + 1022071 = 1022090
31 + 1022059 = 1022090
37 + 1022053 = 1022090
73 + 1022017 = 1022090
79 + 1022011 = 1022090
127 + 1021963 = 1022090
193 + 1021897 = 1022090

Showing the first eight; more decompositions exist.
