Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586876, here are decompositions:

7 + 31586869 = 31586876
37 + 31586839 = 31586876
67 + 31586809 = 31586876
73 + 31586803 = 31586876
157 + 31586719 = 31586876
229 + 31586647 = 31586876
367 + 31586509 = 31586876
379 + 31586497 = 31586876

Showing the first eight; more decompositions exist.
