Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30222, here are decompositions:

11 + 30211 = 30222
19 + 30203 = 30222
41 + 30181 = 30222
53 + 30169 = 30222
61 + 30161 = 30222
83 + 30139 = 30222
89 + 30133 = 30222
103 + 30119 = 30222

Showing the first eight; more decompositions exist.
