Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596168, here are decompositions:

5 + 31596163 = 31596168
17 + 31596151 = 31596168
41 + 31596127 = 31596168
47 + 31596121 = 31596168
101 + 31596067 = 31596168
127 + 31596041 = 31596168
139 + 31596029 = 31596168
179 + 31595989 = 31596168

Showing the first eight; more decompositions exist.
