Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188112, here are decompositions:

5 + 188107 = 188112
83 + 188029 = 188112
101 + 188011 = 188112
139 + 187973 = 188112
149 + 187963 = 188112
181 + 187931 = 188112
191 + 187921 = 188112
229 + 187883 = 188112

Showing the first eight; more decompositions exist.
