Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158556, here are decompositions:

5 + 158551 = 158556
19 + 158537 = 158556
29 + 158527 = 158556
37 + 158519 = 158556
67 + 158489 = 158556
107 + 158449 = 158556
113 + 158443 = 158556
127 + 158429 = 158556

Showing the first eight; more decompositions exist.
