Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111080, here are decompositions:

31 + 111049 = 111080
37 + 111043 = 111080
103 + 110977 = 111080
157 + 110923 = 111080
163 + 110917 = 111080
181 + 110899 = 111080
199 + 110881 = 111080
331 + 110749 = 111080

Showing the first eight; more decompositions exist.
