Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586514, here are decompositions:

5 + 31586509 = 31586514
13 + 31586501 = 31586514
17 + 31586497 = 31586514
31 + 31586483 = 31586514
41 + 31586473 = 31586514
53 + 31586461 = 31586514
67 + 31586447 = 31586514
107 + 31586407 = 31586514

Showing the first eight; more decompositions exist.
