Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189994, here are decompositions:

5 + 189989 = 189994
11 + 189983 = 189994
17 + 189977 = 189994
47 + 189947 = 189994
107 + 189887 = 189994
113 + 189881 = 189994
197 + 189797 = 189994
227 + 189767 = 189994

Showing the first eight; more decompositions exist.
