Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111828, here are decompositions:

7 + 111821 = 111828
29 + 111799 = 111828
37 + 111791 = 111828
47 + 111781 = 111828
61 + 111767 = 111828
97 + 111731 = 111828
107 + 111721 = 111828
131 + 111697 = 111828

Showing the first eight; more decompositions exist.
