Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586364, here are decompositions:

13 + 31586351 = 31586364
53 + 31586311 = 31586364
83 + 31586281 = 31586364
107 + 31586257 = 31586364
127 + 31586237 = 31586364
193 + 31586171 = 31586364
223 + 31586141 = 31586364
233 + 31586131 = 31586364

Showing the first eight; more decompositions exist.
