Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586624, here are decompositions:

7 + 31586617 = 31586624
127 + 31586497 = 31586624
151 + 31586473 = 31586624
163 + 31586461 = 31586624
313 + 31586311 = 31586624
337 + 31586287 = 31586624
367 + 31586257 = 31586624
523 + 31586101 = 31586624

Showing the first eight; more decompositions exist.
