Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111818, here are decompositions:

19 + 111799 = 111818
37 + 111781 = 111818
67 + 111751 = 111818
97 + 111721 = 111818
151 + 111667 = 111818
181 + 111637 = 111818
241 + 111577 = 111818
331 + 111487 = 111818

Showing the first eight; more decompositions exist.
