Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111866, here are decompositions:

3 + 111863 = 111866
19 + 111847 = 111866
37 + 111829 = 111866
67 + 111799 = 111866
199 + 111667 = 111866
229 + 111637 = 111866
373 + 111493 = 111866
379 + 111487 = 111866

Showing the first eight; more decompositions exist.
