Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158680, here are decompositions:

17 + 158663 = 158680
23 + 158657 = 158680
47 + 158633 = 158680
59 + 158621 = 158680
83 + 158597 = 158680
89 + 158591 = 158680
107 + 158573 = 158680
113 + 158567 = 158680

Showing the first eight; more decompositions exist.
