Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596580, here are decompositions:

83 + 31596497 = 31596580
107 + 31596473 = 31596580
167 + 31596413 = 31596580
179 + 31596401 = 31596580
263 + 31596317 = 31596580
269 + 31596311 = 31596580
461 + 31596119 = 31596580
773 + 31595807 = 31596580

Showing the first eight; more decompositions exist.
