Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586226, here are decompositions:

79 + 31586147 = 31586226
149 + 31586077 = 31586226
167 + 31586059 = 31586226
173 + 31586053 = 31586226
223 + 31586003 = 31586226
229 + 31585997 = 31586226
263 + 31585963 = 31586226
337 + 31585889 = 31586226

Showing the first eight; more decompositions exist.
