Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111218, here are decompositions:

7 + 111211 = 111218
31 + 111187 = 111218
97 + 111121 = 111218
109 + 111109 = 111218
127 + 111091 = 111218
229 + 110989 = 111218
241 + 110977 = 111218
271 + 110947 = 111218

Showing the first eight; more decompositions exist.
