Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586324, here are decompositions:

13 + 31586311 = 31586324
37 + 31586287 = 31586324
43 + 31586281 = 31586324
67 + 31586257 = 31586324
193 + 31586131 = 31586324
223 + 31586101 = 31586324
271 + 31586053 = 31586324
421 + 31585903 = 31586324

Showing the first eight; more decompositions exist.
