Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179740, here are decompositions:

3 + 179737 = 179740
23 + 179717 = 179740
47 + 179693 = 179740
53 + 179687 = 179740
83 + 179657 = 179740
89 + 179651 = 179740
107 + 179633 = 179740
137 + 179603 = 179740

Showing the first eight; more decompositions exist.
