Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022212, here are decompositions:

3 + 1022209 = 1022212
11 + 1022201 = 1022212
29 + 1022183 = 1022212
71 + 1022141 = 1022212
83 + 1022129 = 1022212
89 + 1022123 = 1022212
179 + 1022033 = 1022212
239 + 1021973 = 1022212

Showing the first eight; more decompositions exist.
