Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87660, here are decompositions:

11 + 87649 = 87660
17 + 87643 = 87660
19 + 87641 = 87660
29 + 87631 = 87660
31 + 87629 = 87660
37 + 87623 = 87660
47 + 87613 = 87660
71 + 87589 = 87660

Showing the first eight; more decompositions exist.
