Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019222, here are decompositions:

13 + 1019209 = 1019222
103 + 1019119 = 1019222
151 + 1019071 = 1019222
163 + 1019059 = 1019222
199 + 1019023 = 1019222
223 + 1018999 = 1019222
229 + 1018993 = 1019222
241 + 1018981 = 1019222

Showing the first eight; more decompositions exist.
