Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188800, here are decompositions:

47 + 188753 = 188800
71 + 188729 = 188800
89 + 188711 = 188800
107 + 188693 = 188800
113 + 188687 = 188800
167 + 188633 = 188800
179 + 188621 = 188800
191 + 188609 = 188800

Showing the first eight; more decompositions exist.
