Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586134, here are decompositions:

3 + 31586131 = 31586134
131 + 31586003 = 31586134
137 + 31585997 = 31586134
197 + 31585937 = 31586134
311 + 31585823 = 31586134
317 + 31585817 = 31586134
353 + 31585781 = 31586134
383 + 31585751 = 31586134

Showing the first eight; more decompositions exist.
