Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111788, here are decompositions:

7 + 111781 = 111788
37 + 111751 = 111788
67 + 111721 = 111788
151 + 111637 = 111788
211 + 111577 = 111788
349 + 111439 = 111788
379 + 111409 = 111788
487 + 111301 = 111788

Showing the first eight; more decompositions exist.
