Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545332, here are decompositions:

3 + 31545329 = 31545332
151 + 31545181 = 31545332
241 + 31545091 = 31545332
271 + 31545061 = 31545332
283 + 31545049 = 31545332
331 + 31545001 = 31545332
409 + 31544923 = 31545332
433 + 31544899 = 31545332

Showing the first eight; more decompositions exist.
