Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586196, here are decompositions:

137 + 31586059 = 31586196
139 + 31586057 = 31586196
193 + 31586003 = 31586196
199 + 31585997 = 31586196
223 + 31585973 = 31586196
233 + 31585963 = 31586196
293 + 31585903 = 31586196
307 + 31585889 = 31586196

Showing the first eight; more decompositions exist.
