Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111904, here are decompositions:

11 + 111893 = 111904
41 + 111863 = 111904
47 + 111857 = 111904
71 + 111833 = 111904
83 + 111821 = 111904
113 + 111791 = 111904
131 + 111773 = 111904
137 + 111767 = 111904

Showing the first eight; more decompositions exist.
