Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173790, here are decompositions:

7 + 173783 = 173790
11 + 173779 = 173790
13 + 173777 = 173790
17 + 173773 = 173790
47 + 173743 = 173790
61 + 173729 = 173790
83 + 173707 = 173790
103 + 173687 = 173790

Showing the first eight; more decompositions exist.
