Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022228, here are decompositions:

19 + 1022209 = 1022228
37 + 1022191 = 1022228
61 + 1022167 = 1022228
157 + 1022071 = 1022228
211 + 1022017 = 1022228
331 + 1021897 = 1022228
349 + 1021879 = 1022228
367 + 1021861 = 1022228

Showing the first eight; more decompositions exist.
