Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111838, here are decompositions:

5 + 111833 = 111838
11 + 111827 = 111838
17 + 111821 = 111838
47 + 111791 = 111838
59 + 111779 = 111838
71 + 111767 = 111838
107 + 111731 = 111838
179 + 111659 = 111838

Showing the first eight; more decompositions exist.
