Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158664, here are decompositions:

7 + 158657 = 158664
17 + 158647 = 158664
31 + 158633 = 158664
43 + 158621 = 158664
47 + 158617 = 158664
53 + 158611 = 158664
67 + 158597 = 158664
73 + 158591 = 158664

Showing the first eight; more decompositions exist.
