Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159906, here are decompositions:

7 + 159899 = 159906
37 + 159869 = 159906
53 + 159853 = 159906
67 + 159839 = 159906
73 + 159833 = 159906
107 + 159799 = 159906
113 + 159793 = 159906
127 + 159779 = 159906

Showing the first eight; more decompositions exist.
