Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7232, here are decompositions:

3 + 7229 = 7232
13 + 7219 = 7232
19 + 7213 = 7232
73 + 7159 = 7232
103 + 7129 = 7232
163 + 7069 = 7232
193 + 7039 = 7232
241 + 6991 = 7232

Showing the first eight; more decompositions exist.
