Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173858, here are decompositions:

7 + 173851 = 173858
19 + 173839 = 173858
31 + 173827 = 173858
79 + 173779 = 173858
151 + 173707 = 173858
199 + 173659 = 173858
211 + 173647 = 173858
229 + 173629 = 173858

Showing the first eight; more decompositions exist.
