Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596374, here are decompositions:

67 + 31596307 = 31596374
181 + 31596193 = 31596374
211 + 31596163 = 31596374
223 + 31596151 = 31596374
307 + 31596067 = 31596374
367 + 31596007 = 31596374
541 + 31595833 = 31596374
643 + 31595731 = 31596374

Showing the first eight; more decompositions exist.
