Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595536, here are decompositions:

53 + 31595483 = 31595536
149 + 31595387 = 31595536
173 + 31595363 = 31595536
257 + 31595279 = 31595536
263 + 31595273 = 31595536
293 + 31595243 = 31595536
317 + 31595219 = 31595536
347 + 31595189 = 31595536

Showing the first eight; more decompositions exist.
