Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87710, here are decompositions:

13 + 87697 = 87710
19 + 87691 = 87710
31 + 87679 = 87710
61 + 87649 = 87710
67 + 87643 = 87710
79 + 87631 = 87710
97 + 87613 = 87710
127 + 87583 = 87710

Showing the first eight; more decompositions exist.
