Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20432, here are decompositions:

43 + 20389 = 20432
73 + 20359 = 20432
79 + 20353 = 20432
109 + 20323 = 20432
163 + 20269 = 20432
199 + 20233 = 20432
271 + 20161 = 20432
283 + 20149 = 20432

Showing the first eight; more decompositions exist.
