Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173920, here are decompositions:

3 + 173917 = 173920
11 + 173909 = 173920
23 + 173897 = 173920
29 + 173891 = 173920
53 + 173867 = 173920
59 + 173861 = 173920
101 + 173819 = 173920
113 + 173807 = 173920

Showing the first eight; more decompositions exist.
