Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111042, here are decompositions:

11 + 111031 = 111042
13 + 111029 = 111042
53 + 110989 = 111042
73 + 110969 = 111042
103 + 110939 = 111042
109 + 110933 = 111042
163 + 110879 = 111042
179 + 110863 = 111042

Showing the first eight; more decompositions exist.
