Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87716, here are decompositions:

19 + 87697 = 87716
37 + 87679 = 87716
67 + 87649 = 87716
73 + 87643 = 87716
103 + 87613 = 87716
127 + 87589 = 87716
157 + 87559 = 87716
163 + 87553 = 87716

Showing the first eight; more decompositions exist.
