Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509332, here are decompositions:

3 + 31509329 = 31509332
61 + 31509271 = 31509332
163 + 31509169 = 31509332
193 + 31509139 = 31509332
241 + 31509091 = 31509332
271 + 31509061 = 31509332
373 + 31508959 = 31509332
541 + 31508791 = 31509332

Showing the first eight; more decompositions exist.
