Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87960, here are decompositions:

17 + 87943 = 87960
29 + 87931 = 87960
43 + 87917 = 87960
73 + 87887 = 87960
79 + 87881 = 87960
83 + 87877 = 87960
107 + 87853 = 87960
127 + 87833 = 87960

Showing the first eight; more decompositions exist.
