Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87708, here are decompositions:

7 + 87701 = 87708
11 + 87697 = 87708
17 + 87691 = 87708
29 + 87679 = 87708
37 + 87671 = 87708
59 + 87649 = 87708
67 + 87641 = 87708
79 + 87629 = 87708

Showing the first eight; more decompositions exist.
