Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1960, here are decompositions:

11 + 1949 = 1960
29 + 1931 = 1960
47 + 1913 = 1960
53 + 1907 = 1960
59 + 1901 = 1960
71 + 1889 = 1960
83 + 1877 = 1960
89 + 1871 = 1960

Showing the first eight; more decompositions exist.
