Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129396, here are decompositions:

17 + 129379 = 129396
83 + 129313 = 129396
103 + 129293 = 129396
107 + 129289 = 129396
109 + 129287 = 129396
167 + 129229 = 129396
173 + 129223 = 129396
199 + 129197 = 129396

Showing the first eight; more decompositions exist.
