Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586954, here are decompositions:

13 + 31586941 = 31586954
151 + 31586803 = 31586954
163 + 31586791 = 31586954
211 + 31586743 = 31586954
283 + 31586671 = 31586954
307 + 31586647 = 31586954
337 + 31586617 = 31586954
457 + 31586497 = 31586954

Showing the first eight; more decompositions exist.
