Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87768, here are decompositions:

17 + 87751 = 87768
29 + 87739 = 87768
47 + 87721 = 87768
67 + 87701 = 87768
71 + 87697 = 87768
89 + 87679 = 87768
97 + 87671 = 87768
127 + 87641 = 87768

Showing the first eight; more decompositions exist.
