Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596144, here are decompositions:

17 + 31596127 = 31596144
23 + 31596121 = 31596144
103 + 31596041 = 31596144
137 + 31596007 = 31596144
263 + 31595881 = 31596144
271 + 31595873 = 31596144
277 + 31595867 = 31596144
311 + 31595833 = 31596144

Showing the first eight; more decompositions exist.
