Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87656, here are decompositions:

7 + 87649 = 87656
13 + 87643 = 87656
43 + 87613 = 87656
67 + 87589 = 87656
73 + 87583 = 87656
97 + 87559 = 87656
103 + 87553 = 87656
109 + 87547 = 87656

Showing the first eight; more decompositions exist.
