Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188958, here are decompositions:

5 + 188953 = 188958
17 + 188941 = 188958
19 + 188939 = 188958
31 + 188927 = 188958
47 + 188911 = 188958
67 + 188891 = 188958
89 + 188869 = 188958
97 + 188861 = 188958

Showing the first eight; more decompositions exist.
