Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102226, here are decompositions:

23 + 102203 = 102226
29 + 102197 = 102226
149 + 102077 = 102226
167 + 102059 = 102226
227 + 101999 = 102226
239 + 101987 = 102226
263 + 101963 = 102226
269 + 101957 = 102226

Showing the first eight; more decompositions exist.
