Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158030, here are decompositions:

13 + 158017 = 158030
31 + 157999 = 158030
79 + 157951 = 158030
97 + 157933 = 158030
163 + 157867 = 158030
193 + 157837 = 158030
199 + 157831 = 158030
283 + 157747 = 158030

Showing the first eight; more decompositions exist.
