Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602960, here are decompositions:

29 + 31602931 = 31602960
43 + 31602917 = 31602960
61 + 31602899 = 31602960
83 + 31602877 = 31602960
97 + 31602863 = 31602960
101 + 31602859 = 31602960
107 + 31602853 = 31602960
157 + 31602803 = 31602960

Showing the first eight; more decompositions exist.
