Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173826, here are decompositions:

7 + 173819 = 173826
19 + 173807 = 173826
43 + 173783 = 173826
47 + 173779 = 173826
53 + 173773 = 173826
83 + 173743 = 173826
97 + 173729 = 173826
113 + 173713 = 173826

Showing the first eight; more decompositions exist.
