Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111864, here are decompositions:

7 + 111857 = 111864
17 + 111847 = 111864
31 + 111833 = 111864
37 + 111827 = 111864
43 + 111821 = 111864
73 + 111791 = 111864
83 + 111781 = 111864
97 + 111767 = 111864

Showing the first eight; more decompositions exist.
