Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32240, here are decompositions:

3 + 32237 = 32240
7 + 32233 = 32240
37 + 32203 = 32240
67 + 32173 = 32240
97 + 32143 = 32240
151 + 32089 = 32240
157 + 32083 = 32240
163 + 32077 = 32240

Showing the first eight; more decompositions exist.
