Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022210, here are decompositions:

19 + 1022191 = 1022210
31 + 1022179 = 1022210
43 + 1022167 = 1022210
73 + 1022137 = 1022210
97 + 1022113 = 1022210
127 + 1022083 = 1022210
139 + 1022071 = 1022210
151 + 1022059 = 1022210

Showing the first eight; more decompositions exist.
