Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042222, here are decompositions:

11 + 1042211 = 1042222
29 + 1042193 = 1042222
89 + 1042133 = 1042222
101 + 1042121 = 1042222
113 + 1042109 = 1042222
131 + 1042091 = 1042222
179 + 1042043 = 1042222
239 + 1041983 = 1042222

Showing the first eight; more decompositions exist.
