Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78432, here are decompositions:

5 + 78427 = 78432
31 + 78401 = 78432
131 + 78301 = 78432
149 + 78283 = 78432
173 + 78259 = 78432
191 + 78241 = 78432
199 + 78233 = 78432
229 + 78203 = 78432

Showing the first eight; more decompositions exist.
