Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168030, here are decompositions:

7 + 168023 = 168030
17 + 168013 = 168030
43 + 167987 = 168030
59 + 167971 = 168030
113 + 167917 = 168030
131 + 167899 = 168030
139 + 167891 = 168030
151 + 167879 = 168030

Showing the first eight; more decompositions exist.
