Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40432, here are decompositions:

3 + 40429 = 40432
5 + 40427 = 40432
71 + 40361 = 40432
89 + 40343 = 40432
149 + 40283 = 40432
179 + 40253 = 40432
191 + 40241 = 40432
239 + 40193 = 40432

Showing the first eight; more decompositions exist.
