Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87666, here are decompositions:

17 + 87649 = 87666
23 + 87643 = 87666
37 + 87629 = 87666
43 + 87623 = 87666
53 + 87613 = 87666
79 + 87587 = 87666
83 + 87583 = 87666
107 + 87559 = 87666

Showing the first eight; more decompositions exist.
