Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159930, here are decompositions:

19 + 159911 = 159930
31 + 159899 = 159930
59 + 159871 = 159930
61 + 159869 = 159930
73 + 159857 = 159930
97 + 159833 = 159930
131 + 159799 = 159930
137 + 159793 = 159930

Showing the first eight; more decompositions exist.
