Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102422, here are decompositions:

13 + 102409 = 102422
163 + 102259 = 102422
181 + 102241 = 102422
193 + 102229 = 102422
223 + 102199 = 102422
241 + 102181 = 102422
283 + 102139 = 102422
379 + 102043 = 102422

Showing the first eight; more decompositions exist.
