Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596500, here are decompositions:

3 + 31596497 = 31596500
97 + 31596403 = 31596500
109 + 31596391 = 31596500
193 + 31596307 = 31596500
307 + 31596193 = 31596500
337 + 31596163 = 31596500
349 + 31596151 = 31596500
373 + 31596127 = 31596500

Showing the first eight; more decompositions exist.
