Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111986, here are decompositions:

13 + 111973 = 111986
37 + 111949 = 111986
67 + 111919 = 111986
73 + 111913 = 111986
139 + 111847 = 111986
157 + 111829 = 111986
349 + 111637 = 111986
409 + 111577 = 111986

Showing the first eight; more decompositions exist.
