Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111290, here are decompositions:

19 + 111271 = 111290
37 + 111253 = 111290
61 + 111229 = 111290
73 + 111217 = 111290
79 + 111211 = 111290
103 + 111187 = 111290
163 + 111127 = 111290
181 + 111109 = 111290

Showing the first eight; more decompositions exist.
