Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188120, here are decompositions:

13 + 188107 = 188120
103 + 188017 = 188120
109 + 188011 = 188120
157 + 187963 = 188120
193 + 187927 = 188120
199 + 187921 = 188120
211 + 187909 = 188120
223 + 187897 = 188120

Showing the first eight; more decompositions exist.
