Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173820, here are decompositions:

13 + 173807 = 173820
37 + 173783 = 173820
41 + 173779 = 173820
43 + 173777 = 173820
47 + 173773 = 173820
79 + 173741 = 173820
107 + 173713 = 173820
113 + 173707 = 173820

Showing the first eight; more decompositions exist.
