Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87864, here are decompositions:

11 + 87853 = 87864
31 + 87833 = 87864
53 + 87811 = 87864
61 + 87803 = 87864
67 + 87797 = 87864
71 + 87793 = 87864
97 + 87767 = 87864
113 + 87751 = 87864

Showing the first eight; more decompositions exist.
