Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102222, here are decompositions:

5 + 102217 = 102222
19 + 102203 = 102222
23 + 102199 = 102222
31 + 102191 = 102222
41 + 102181 = 102222
61 + 102161 = 102222
73 + 102149 = 102222
83 + 102139 = 102222

Showing the first eight; more decompositions exist.
