Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156960, here are decompositions:

17 + 156943 = 156960
19 + 156941 = 156960
47 + 156913 = 156960
59 + 156901 = 156960
61 + 156899 = 156960
73 + 156887 = 156960
127 + 156833 = 156960
137 + 156823 = 156960

Showing the first eight; more decompositions exist.
