Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042216, here are decompositions:

5 + 1042211 = 1042216
23 + 1042193 = 1042216
29 + 1042187 = 1042216
83 + 1042133 = 1042216
107 + 1042109 = 1042216
113 + 1042103 = 1042216
173 + 1042043 = 1042216
233 + 1041983 = 1042216

Showing the first eight; more decompositions exist.
