Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188994, here are decompositions:

11 + 188983 = 188994
37 + 188957 = 188994
41 + 188953 = 188994
53 + 188941 = 188994
61 + 188933 = 188994
67 + 188927 = 188994
83 + 188911 = 188994
103 + 188891 = 188994

Showing the first eight; more decompositions exist.
