Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72432, here are decompositions:

11 + 72421 = 72432
53 + 72379 = 72432
79 + 72353 = 72432
163 + 72269 = 72432
179 + 72253 = 72432
181 + 72251 = 72432
211 + 72221 = 72432
263 + 72169 = 72432

Showing the first eight; more decompositions exist.
