Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188964, here are decompositions:

7 + 188957 = 188964
11 + 188953 = 188964
23 + 188941 = 188964
31 + 188933 = 188964
37 + 188927 = 188964
53 + 188911 = 188964
73 + 188891 = 188964
101 + 188863 = 188964

Showing the first eight; more decompositions exist.
