Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179920, here are decompositions:

3 + 179917 = 179920
11 + 179909 = 179920
17 + 179903 = 179920
23 + 179897 = 179920
71 + 179849 = 179920
101 + 179819 = 179920
107 + 179813 = 179920
113 + 179807 = 179920

Showing the first eight; more decompositions exist.
