Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028222, here are decompositions:

31 + 1028191 = 1028222
73 + 1028149 = 1028222
109 + 1028113 = 1028222
193 + 1028029 = 1028222
199 + 1028023 = 1028222
211 + 1028011 = 1028222
331 + 1027891 = 1028222
439 + 1027783 = 1028222

Showing the first eight; more decompositions exist.
