Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532304, here are decompositions:

43 + 31532261 = 31532304
101 + 31532203 = 31532304
137 + 31532167 = 31532304
163 + 31532141 = 31532304
191 + 31532113 = 31532304
233 + 31532071 = 31532304
241 + 31532063 = 31532304
283 + 31532021 = 31532304

Showing the first eight; more decompositions exist.
