Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158616, here are decompositions:

5 + 158611 = 158616
19 + 158597 = 158616
43 + 158573 = 158616
53 + 158563 = 158616
79 + 158537 = 158616
89 + 158527 = 158616
97 + 158519 = 158616
109 + 158507 = 158616

Showing the first eight; more decompositions exist.
