Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183988, here are decompositions:

17 + 183971 = 183988
29 + 183959 = 183988
71 + 183917 = 183988
107 + 183881 = 183988
179 + 183809 = 183988
191 + 183797 = 183988
227 + 183761 = 183988
281 + 183707 = 183988

Showing the first eight; more decompositions exist.
