Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111138, here are decompositions:

11 + 111127 = 111138
17 + 111121 = 111138
19 + 111119 = 111138
29 + 111109 = 111138
47 + 111091 = 111138
89 + 111049 = 111138
107 + 111031 = 111138
109 + 111029 = 111138

Showing the first eight; more decompositions exist.
