Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173980, here are decompositions:

3 + 173977 = 173980
11 + 173969 = 173980
47 + 173933 = 173980
71 + 173909 = 173980
83 + 173897 = 173980
89 + 173891 = 173980
113 + 173867 = 173980
173 + 173807 = 173980

Showing the first eight; more decompositions exist.
