Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111186, here are decompositions:

37 + 111149 = 111186
43 + 111143 = 111186
59 + 111127 = 111186
67 + 111119 = 111186
83 + 111103 = 111186
137 + 111049 = 111186
157 + 111029 = 111186
197 + 110989 = 111186

Showing the first eight; more decompositions exist.
