Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159912, here are decompositions:

13 + 159899 = 159912
41 + 159871 = 159912
43 + 159869 = 159912
59 + 159853 = 159912
73 + 159839 = 159912
79 + 159833 = 159912
101 + 159811 = 159912
113 + 159799 = 159912

Showing the first eight; more decompositions exist.
