Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111028, here are decompositions:

59 + 110969 = 111028
89 + 110939 = 111028
101 + 110927 = 111028
107 + 110921 = 111028
149 + 110879 = 111028
179 + 110849 = 111028
251 + 110777 = 111028
257 + 110771 = 111028

Showing the first eight; more decompositions exist.
