Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586932, here are decompositions:

5 + 31586927 = 31586932
11 + 31586921 = 31586932
29 + 31586903 = 31586932
53 + 31586879 = 31586932
233 + 31586699 = 31586932
263 + 31586669 = 31586932
353 + 31586579 = 31586932
389 + 31586543 = 31586932

Showing the first eight; more decompositions exist.
