Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188980, here are decompositions:

23 + 188957 = 188980
41 + 188939 = 188980
47 + 188933 = 188980
53 + 188927 = 188980
89 + 188891 = 188980
137 + 188843 = 188980
149 + 188831 = 188980
179 + 188801 = 188980

Showing the first eight; more decompositions exist.
