Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596206, here are decompositions:

13 + 31596193 = 31596206
43 + 31596163 = 31596206
79 + 31596127 = 31596206
139 + 31596067 = 31596206
157 + 31596049 = 31596206
199 + 31596007 = 31596206
223 + 31595983 = 31596206
277 + 31595929 = 31596206

Showing the first eight; more decompositions exist.
