Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18960, here are decompositions:

13 + 18947 = 18960
41 + 18919 = 18960
43 + 18917 = 18960
47 + 18913 = 18960
61 + 18899 = 18960
101 + 18859 = 18960
157 + 18803 = 18960
163 + 18797 = 18960

Showing the first eight; more decompositions exist.
