Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188144, here are decompositions:

7 + 188137 = 188144
37 + 188107 = 188144
127 + 188017 = 188144
157 + 187987 = 188144
181 + 187963 = 188144
193 + 187951 = 188144
223 + 187921 = 188144
283 + 187861 = 188144

Showing the first eight; more decompositions exist.
