Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158028, here are decompositions:

11 + 158017 = 158028
19 + 158009 = 158028
29 + 157999 = 158028
37 + 157991 = 158028
97 + 157931 = 158028
127 + 157901 = 158028
131 + 157897 = 158028
139 + 157889 = 158028

Showing the first eight; more decompositions exist.
