Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586676, here are decompositions:

5 + 31586671 = 31586676
7 + 31586669 = 31586676
29 + 31586647 = 31586676
59 + 31586617 = 31586676
97 + 31586579 = 31586676
139 + 31586537 = 31586676
167 + 31586509 = 31586676
179 + 31586497 = 31586676

Showing the first eight; more decompositions exist.
