Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586006, here are decompositions:

3 + 31586003 = 31586006
43 + 31585963 = 31586006
103 + 31585903 = 31586006
157 + 31585849 = 31586006
223 + 31585783 = 31586006
229 + 31585777 = 31586006
409 + 31585597 = 31586006
457 + 31585549 = 31586006

Showing the first eight; more decompositions exist.
