Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596902, here are decompositions:

3 + 31596899 = 31596902
13 + 31596889 = 31596902
19 + 31596883 = 31596902
109 + 31596793 = 31596902
151 + 31596751 = 31596902
193 + 31596709 = 31596902
223 + 31596679 = 31596902
229 + 31596673 = 31596902

Showing the first eight; more decompositions exist.
