Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81466, here are decompositions:

3 + 81463 = 81466
107 + 81359 = 81466
113 + 81353 = 81466
167 + 81299 = 81466
173 + 81293 = 81466
227 + 81239 = 81466
233 + 81233 = 81466
263 + 81203 = 81466

Showing the first eight; more decompositions exist.
