Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158658, here are decompositions:

11 + 158647 = 158658
37 + 158621 = 158658
41 + 158617 = 158658
47 + 158611 = 158658
61 + 158597 = 158658
67 + 158591 = 158658
107 + 158551 = 158658
131 + 158527 = 158658

Showing the first eight; more decompositions exist.
