Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188894, here are decompositions:

3 + 188891 = 188894
31 + 188863 = 188894
37 + 188857 = 188894
61 + 188833 = 188894
67 + 188827 = 188894
103 + 188791 = 188894
127 + 188767 = 188894
193 + 188701 = 188894

Showing the first eight; more decompositions exist.
