Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596658, here are decompositions:

47 + 31596611 = 31596658
239 + 31596419 = 31596658
257 + 31596401 = 31596658
347 + 31596311 = 31596658
449 + 31596209 = 31596658
617 + 31596041 = 31596658
827 + 31595831 = 31596658
881 + 31595777 = 31596658

Showing the first eight; more decompositions exist.
