Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2222, here are decompositions:

19 + 2203 = 2222
43 + 2179 = 2222
61 + 2161 = 2222
79 + 2143 = 2222
109 + 2113 = 2222
139 + 2083 = 2222
193 + 2029 = 2222
211 + 2011 = 2222

Showing the first eight; more decompositions exist.
