Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87828, here are decompositions:

17 + 87811 = 87828
31 + 87797 = 87828
61 + 87767 = 87828
89 + 87739 = 87828
107 + 87721 = 87828
109 + 87719 = 87828
127 + 87701 = 87828
131 + 87697 = 87828

Showing the first eight; more decompositions exist.
