Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42960, here are decompositions:

7 + 42953 = 42960
17 + 42943 = 42960
23 + 42937 = 42960
31 + 42929 = 42960
37 + 42923 = 42960
59 + 42901 = 42960
61 + 42899 = 42960
97 + 42863 = 42960

Showing the first eight; more decompositions exist.
