Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111938, here are decompositions:

19 + 111919 = 111938
67 + 111871 = 111938
109 + 111829 = 111938
139 + 111799 = 111938
157 + 111781 = 111938
241 + 111697 = 111938
271 + 111667 = 111938
499 + 111439 = 111938

Showing the first eight; more decompositions exist.
