Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021222, here are decompositions:

5 + 1021217 = 1021222
23 + 1021199 = 1021222
131 + 1021091 = 1021222
149 + 1021073 = 1021222
179 + 1021043 = 1021222
233 + 1020989 = 1021222
263 + 1020959 = 1021222
383 + 1020839 = 1021222

Showing the first eight; more decompositions exist.
