Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159918, here are decompositions:

7 + 159911 = 159918
19 + 159899 = 159918
47 + 159871 = 159918
61 + 159857 = 159918
79 + 159839 = 159918
107 + 159811 = 159918
127 + 159791 = 159918
131 + 159787 = 159918

Showing the first eight; more decompositions exist.
