Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586694, here are decompositions:

5 + 31586689 = 31586694
23 + 31586671 = 31586694
47 + 31586647 = 31586694
67 + 31586627 = 31586694
103 + 31586591 = 31586694
151 + 31586543 = 31586694
157 + 31586537 = 31586694
193 + 31586501 = 31586694

Showing the first eight; more decompositions exist.
